[AArch64] Tighten move constraints for symbolic operands

The movsi and movdi constraints allowed the source to be any
absolute symbolic expression ("S").  That's OK for operands that
have already been vetted by the aarch64_mov_operand predicate but
causes problems if the register allocator substitutes an equivalence
(the usual "the constraints can't accept more than the predicates"
restriction).

Although all other uses of "S" in the backend are redundant and could
in principle be removed, "S" itself is a publicly-documented constraint
and so we'd have to keep its definition.  This patch therefore adds a
new "Usa" constraint for legitimate absolute address operands.

Record equivalences for spill registers

If we decide to allocate a call-clobbered register R to a value that
is live across a call, LRA will create a new spill register TMPR,
insert:

   TMPR <- R

before the call and

   R <- TMPR

after it.  But if we then failed to allocate a register to TMPR, we would
always spill it to the stack, even if R was known to be equivalent to
a constant or to some existing memory location.  And on AArch64, we'd
always fail to allocate such a register for 128-bit Advanced SIMD modes,
since no registers of those modes are call-preserved.

This patch avoids the problem by copying the equivalence information
from the original pseudo to the spill register.  It means that the
code for the testcase is as good with -O2 as it is with -O,
whereas previously the -O code was better.

diagnostic.c: add print_option_information

This patch simplifies diagnostic_report_diagnostic by moving
option-printing to a new subroutine.

Doing so required a slight rewrite.  In both the old and new
code, context->option_name returns a malloc-ed string.
The old behavior was to then use ACONCAT to manipulate the
format_spec, appending the option metadata.
ACONCAT calcs the buffer size, then uses alloca, and then copies the
data to the on-stack buffer.

Given the alloca, this needs rewriting when moving the printing to
a subroutine.  In the new version, the metadata is simply printed
using pp_* calls (so it's hitting the obstack within the
pretty_printer).

This means we can get rid of the save/restore of format_spec: I don't
believe anything else in the code modifies it.

It also seems inherently simpler; it seems odd to me to be
appending metadata to the formatting string, rather than simply
printing the metadata after the formatted string is printed
(the old code also assumed that no option name contained a '%').

No functional change intended.

gcc/ChangeLog:
* diagnostic.c (diagnostic_report_diagnostic): Eliminate
save/restor of format_spec.  Move option-printing code to...

With -mcpu=generic the loop alignment is currently 4.  All but one of the

on several cores, it is best to use that by default.  As discussed in [1],
the jump alignment has no effect on performance, yet has a relatively high

Cap niter_for_unrolled_loop to upper bound

For the reasons explained in PR77536, niter_for_unrolled_loop assumes 5
iterations in the absence of profiling information, although it doesn't
increase beyond the estimate for the original loop.  This left a hole in
which the new estimate could be less than the old one but still greater
than the limit imposed by CEIL (nb_iterations_upper_bound, unroll factor).

[ARM] Rename FPSCR builtins to correct names

The GCC documentation in section 6.60.8 ARM Floating Point Status and
Control Intrinsics states that the FPSCR register can be read and
written to using the intrinsics __builtin_arm_get_fpscr and
__builtin_arm_set_fpscr. However, these are misnamed within GCC itself
and these intrinsic names are not recognised.

This patch corrects the intrinsic names to match the documentation, and
adds tests to verify these intrinsics generate the correct
instructions.
