IBM zSystems: Do not propagate scheduler state across basic blocks [PR108102]

So far we propagate scheduler state across basic blocks within EBBs and
reset the state otherwise.  In certain circumstances the entry block of
an EBB might be empty, i.e., no_real_insns_p is true.  In those cases
scheduler state is not reset and subsequently wrong state is propagated
to following blocks of the same EBB.

Since the performance benefit of tracking state across basic blocks is
questionable on modern hardware, simply reset the state for each basic
block.

Fix also resetting f{p,x}d_longrunning.

ifcvt: Fix regression in aarch64/fcsel_1.c

aarch64/fcsel_1.c contains:

double
f_2 (double a, double b, double c, double d)
{
  if (a > b)
    return c;
  else
    return d;
}

which started failing in the GCC 12 timeframe.  When it passed,
the RTL had the form:

[A]
  (set (reg ret) (reg c))
  (set (pc) (if_then_else (gt ...) (label_ref ret) (pc)))
    edge to ret, fallthru to else
else:
  (set (reg ret) (reg d))
    fallthru to ret
ret:
  ...exit...

i.e. a branch around.  Now the RTL has form:

[B]
  (set (reg ret) (reg d))
  (set (pc) (if_then_else (gt ...) (label_ref then) (pc)))
    edge to then, fallthru to ret
ret:
  ...exit...

then:
  (set (reg ret) (reg c))
    edge to ret

i.e. a branch out.

Both are valid, of course, and there's no easy way to predict
which we'll get.  But ifcvt canonicalises its representation on:

  if (cond) goto fallthru else goto non-fallthru

That is, it canoncalises on the branch-around case for half-diamonds.
It therefore wants to invert the comparison in [B] to get:

  if (...) goto ret else goto then

But that isn't possible for strict FP gt, so the optimisation fails.

Canonicalising on the branch-around case seems like the wrong choice for
half diamonds.  The natural way of expressing a conditional branch is
for the label_ref to be the "then" destination and pc to be the "else"
destination.  And the natural choice of condition seems to be the one
under which extra stuff *is* done, rather than the one under which extra
stuff *isn't* done.  But that decision goes back at least 20 years and
it doesn't seem like a good idea to change it in stage 4.

This patch instead allows the internal structure to store the
condition in inverted form.  For simplicity it handles only
conditional moves, which is the one case that is needed
to fix the known regression.  (There are probably unknown
regressions too, but still.)

RISC-V: Change the generation mode of ADJUST_SP_RTX from gen_insn to gen_SET.

The gen_insn method is used to generate ADJUST_SP_RTX here, which has certain
potential risks:

When the architecture adds pre-processing to `define_insn "adddi3"`, such as
`define_expend "adddi3"`, the gen_expand will be automatically called here,
causing the patern to emit directly, which will cause insn to enter REG_NOTE
for `DWARF` instead of patern.

The following error REG_NOTE occurred:
error: invalid rtl sharing found in the insn:
(insn 19 3 20 2 (parallel [
        ...
        ])
    (expr_list:REG_CFA_ADJUST_CFA
        (insn 18 0 0 (set (reg/f:DI 2 sp)
            (plus:DI (reg/f:DI 2 sp)
                (const_int -16 [0xfffffffffffffff0]))) -1
        (nil))))

In fact, the correct one should be the following:
(insn 19 3 20 2 (parallel [
        ...
        ])
    (expr_list:REG_CFA_ADJUST_CFA
        (set (reg/f:DI 2 sp)
            (plus:DI (reg/f:DI 2 sp)
                (const_int -16 [0xfffffffffffffff0])))))

Following the treatment of arm or other architectures, it is more reasonable to
use gen_SET here.

gcc/ChangeLog:

* config/riscv/riscv.cc (riscv_adjust_libcall_cfi_prologue): Change
gen_add3_insn to gen_rtx_SET.
