Use unsigned arithmetic for demoted vector plus/minus/mult (PR 88064)
As Jakub pointed out, if we narrow a plus, minus or mult operation based
on the number of bits that consumers need, we have to convert a signed
operation to an unsigned one in order to avoid new undefined behaviour.
This patch does that and generalises vect_convert_input and
vect_recog_over_widening_pattern to cope with the extra casts.
(The changes to both functions are covered by existing tests.)

testsuite: turn down verbosity of "process-message"
When debugging a failing test, I typically invoke DejaGnu at
verbosity level 2 (via RUNTESTFLAGS="-v -v dg.exp=something"),
so that DejaGnu prints the command line used to invoke the
compiler; specifically these two sites:
target.exp "Invoking the compiler as "
remote.exp "Executing on $hostname"
which are both verbosity level 2.
Unfortunately I run into an O(n^2) issue with logging from
process-message:
verbose "process-message:\n${dg-messages}" 2
where, as each message each processed, it emits the state
of dg-messages, containing the new message and all messages so far,
leading to exponentially-increasing output at level 2 as more test
messages are added.
This patch papers over the problem by moving the
problematic message to verbosity level 3.

[PR85569] skip constexpr target_expr constructor dummy type conversion
The testcase is the work-around testcase for the PR; even that had
started failing. The problem was that, when unqualifying the type of
a TARGET_EXPR, we'd create a variant of the type, then request the
conversion of the TARGET_EXPR_INITIAL to that variant type. Though
the types are different pointer-wise, they're the same_type_p, so the
resulting modified expr compares cp_tree_equal to the original, which
maybe_constant_value flags as an error. There's no reason to
construct an alternate TARGET_EXPR or CONSTRUCTOR just because of an
equivalent type, except for another spot that expected pointer
equality that would no longer be satisfied. Without relaxing the
assert in constexpr_call_hasher::equal, g++.robertl/eb73.C would

[Ada] A task not executing an entry call consumes an Entry_Call slot
This patch resolves the issue where the ATC Level of a task's first
Entry_Call slot corresponds to a task not currently making an entry
call. Consequently, the first slot is never used to record an entry
call. To resolve this, the ATC Level of a such a task is now one less
than the first index of the Entry_Call array (and as result, the ATC
level corresponding to a completed task is now two less than the first
index of this array).
To aid the maintainability of code using ATC levels new constants are
introduced to represent key ATC nesting levels and comments are
introduce for the ATC level definitions.
As a result of this change, the GNAT Extended Ravenscar Profile now
works with the full runtime. The restricted runtime had assumed that the
first Entry_Call slot would be the only slot used for entry calls and
would only initialise this slot (and
System.Tasking.Protected_Objects.Single_Entry was coded this way).
However, Extended Ravenscar uses the native implementation of
System.Tasking.Protected_Objects where this assumption doesn't hold
until the implementation of this patch. Aside from enabling an extra
nested level, this is main functional change of this patch.
