Add global setter for value/mask pair for SSA names.
This patch provides a way to set the value/mask pair of known bits

instead of throwing away the known 1 bits.
In further clean-ups, I will see if it makes sense to remove
set_nonzero_bits altogether, since it is subsumed by value/mask.
The bit twiddling in union/intersect for the value/mask pair must be
normalized to have the unknown bits with a value of 0 in order to make
the math simpler. Normalizing at construction slowed VRP by 1.5% so I
opted to normalize before updating the bitmask in range-ops, since it
was the only user. However, with upcoming changes there will be
multiple setters of the mask (IPA and CCP), so we need something more
general.

Turn TODO_rebuild_frequencies to a pass
Currently we rebiuild profile_counts from profile_probability after inlining,
because there is a chance that producing large loop nests may get unrealistically
large profile_count values. This is much less of concern when we switched to
new profile_count representation while back.
This propagation can also compensate for profile inconsistencies caused by
optimization passes. Since inliner is followed by basic cleanup passes that
does not use profile, we get more realistic profile by delaying the recomputation
after basic optimizations exposed by inlininig are finished.
This does not fit into TODO machinery, so I turn rebuilding into stand alone
pass and schedule it before first consumer of profile in the optimization
queue.
I also added logic that avoids repropagating when CFG is good and not too close
to overflow. Propagating visits very basic block loop_depth times, so it is
not linear and avoiding it may help a bit.

fortran: Reorder array argument evaluation parts [PR92178]
In the case of an array actual arg passed to a polymorphic array dummy
with INTENT(OUT) attribute, reorder the argument evaluation code to
the following:
- first evaluate arguments' values, and data references,
- deallocate data references associated with an allocatable,
intent(out) dummy,
- create a class container using the freed data references.
The ordering used to be incorrect between the first two items,
when one argument was deallocated before a later argument evaluated
its expression depending on the former argument. r14-2395-gb1079fc88f082d3c5b583c8822c08c5647810259 fixed it by treating
arguments associated with an allocatable, intent(out) dummy in a
separate, later block. This, however, wasn't working either if the data
reference of such an argument was depending on its own content, as
the class container initialization was trying to use deallocated
content.
This change generates class container initialization code in a separate
block, so that it is moved after the deallocation block without moving
the rest of the argument evaluation code.
This alone is not sufficient to fix the problem, because the class
container generation code repeatedly uses the full expression of
the argument at a place where deallocation might have happened
already. This is non-optimal, but may also be invalid, because the data
reference may depend on its own content. In that case the expression
can't be evaluated after the data has been deallocated.
As in the scalar case previously treated, this is fixed by saving
the data reference to a pointer before any deallocation happens,
and then only refering to the pointer. gfc_reset_vptr is updated
to take into account the already evaluated class container if it's
available.
Contrary to the scalar case, one hunk is needed to wrap the parameter
evaluation in a conditional, to avoid regressing in
optional_class_2.f90. This used to be handled by the class wrapper
construction which wrapped the whole code in a conditional. With
this change the class wrapper construction can't see the parameter
evaluation code, so the latter is updated with an additional handling
for optional arguments.

fortran: Factor data references for scalar class argument wrapping [PR92178]
In the case of a scalar actual arg passed to a polymorphic assumed-rank
dummy with INTENT(OUT) attribute, avoid repeatedly evaluating the actual
argument reference by saving a pointer to it. This is non-optimal, but
may also be invalid, because the data reference may depend on its own
content. In that case the expression can't be evaluated after the data
has been deallocated.
There are two ways redundant expressions are generated:
- parmse.expr, which contains the actual argument expression, is
reused to get or set subfields in gfc_conv_class_to_class.
- gfc_conv_class_to_class, to get the virtual table pointer associated
with the argument, generates a new expression from scratch starting
with the frontend expression.
The first part is fixed by saving parmse.expr to a pointer and using
the pointer instead of the original expression.
The second part is fixed by adding a separate field to gfc_se that
is set to the class container expression when the expression to
evaluate is polymorphic. This needs the same field in gfc_ss_info
so that its value can be propagated to gfc_conv_class_to_class which
is modified to use that value. Finally gfc_conv_procedure saves the
expression in that field to a pointer in between to avoid the same
problem as for the first part.

fortran: defer class wrapper initialization after deallocation [PR92178]
If an actual argument is associated with an INTENT(OUT) dummy, and code
to deallocate it is generated, generate the class wrapper initialization
after the actual argument deallocation.
This is achieved by passing a cleaned up expression to
gfc_conv_class_to_class, so that the class wrapper initialization code
can be isolated and moved independently after the deallocation.

All tree arguments to the PHI have the same number of occurrences, namely 1,
however it makes a big difference which comparison we test first.
Sorting only on occurrences we'll pick the compares coming from BB 18 and BB 17,
This means we end up generating 4 comparisons, while 2 would have been enough.
By keeping track of the "complexity" of the COND in each BB, (i.e. the number
of comparisons needed to traverse from the start [BB 15] to end [BB 19]) and
using a key tuple of <occurrences, complexity> we end up selecting the compare
from BB 16 and BB 18 first. BB 16 only requires 1 compare, and BB 18, after we
test BB 16 also only requires one additional compare. This change paired with
the one previous above results in the optimal 2 compares.
Most of the comparisons are still needed because the chain of
occurrences to not negate eachother. i.e. _80 is _73 & vr_15 >= -20 and
_85 is _73 & vr_15 < -20. clearly given _73 needs to be true in both branches,
the only additional test needed is on vr_15, where the one test is the negation
of the other. So we don't need to do the comparison of _73 twice.
The changes in the patch reduces the overall number of compares by one, but has
a bigger effect on the dependency chain.
Previously we would generate 5 instructions chain:
As explained in that commit, ifconvert sorts PHI args in increasing number of
occurrences in order to reduce the number of comparisons done while
traversing the tree.
The remaining task that this patch fixes is dealing with the long chain of
comparisons that can be created from phi nodes, particularly when they share
any common successor (classical example is a diamond node).
on a PHI-node the true and else branches carry a condition, true will
carry `a` and false `~a`. The issue is that at the moment GCC tests both `a`
and `~a` when the phi node has more than 2 arguments. Clearly this isn't
needed. The deeper the nesting of phi nodes the larger the repetition.
As an example, for
foo (int *f, int d, int e)
{
for (int i = 0; i < 1024; i++)
{
int a = f[i];
int t;
if (a < 0)
t = 1;
else if (a < e)
t = 1 - a * d;
else
t = 0;
f[i] = t;
}
}
Which correctly elides the test of _21. This is done by borrowing the
vectorizer's helper functions to limit predicate mask usages. Ifcvt will chain
conditionals on the false edge (unless specifically inverted) so this patch on
creating cond a ? b : c, will register ~a when traversing c. If c is a
conditional then c will be simplified to the smaller possible predicate given
the assumptions we already know to be true.

Release symbols in reversed order wrt the order they were allocated.
This fixes an error recovery ICE in the case of a misplaced

which should be immediately released as the declaration is
rejected. This breaks if the derived type is released first.
As the type parameter symbols are in the namespace of the derived
type, releasing the derived type releases the type parameters, so
one can't access them after that, even to release them. Hence,
the type parameters should be released first.

To be more specific, for the given test case, for memory

count of generated vector loads basing from b. This costing
change makes cost model analysis feel it's not profitable
to vectorize the first loop, so this patch adjusts the test
case without vect cost model any more.
