[ARM] Rewire -mfpu=fp-armv8 as VFPv5 + D32 + DP

fp-armv8 is currently defined as a double precision FPv5 with 32 D
registers *and* a special FP_ARMv8 bit. However FP for ARMv8 should only
bring 32 D registers on top of FPv5-D16 so this FP_ARMv8 bit is
spurious. As a consequence, many instruction patterns which are guarded
by TARGET_FPU_ARMV8 are unavailable to FPv5-D16 and FPv5-SP-D16.

This commit gets rid of TARGET_FPU_ARMV8 and rewire all uses to
expressions based on TARGET_VFP5, TARGET_VFPD32 and TARGET_VFP_DOUBLE.

diagnostics: fix crash when consolidating out-of-order fix-it hints (PR c/81405)

PR c/81405 identifies a crash when printing fix-it hints from
-Wmissing-braces when there are excess elements.

The fix-it hints are bogus (which I've filed separately as PR c/81432),
but they lead to a crash within the fix-it consolidation logic I added
in r247548, in line_corrections::add_hint.

The root cause is that some of the fix-it hints are out-of-order
with respect to the column numbers they affect, which can lead to negative
values when computing the gap between the fix-it hints, leading to bogus
memcpy calls that generate out-of-bounds buffer accesses.

The fix is to sort the fix-it hints after filtering them, ensuring that
the gap >= 0.  The patch also adds numerous assertions to the code, both
directly, and by moving the memcpy calls and their args behind
interfaces (themselves containing gcc_assert).

This fixes the crash; it doesn't fix the bug in -Wmissing-braces that
leads to the bogus hints.

S/390: Remove loc splitter

The backend splitter splitting a 3 operand load on condition into 2 is
wrong.  The S/390 load on condition instruction might trap on the
memory operand even if the condition is false.  So if the first load
on condition overwrites a register used as part of the memory address
of the second the second might trigger a segfault even if it does not
actually perform the load.

Trying to fix this I noticed that the generated code looks anyway
better without the splitter.  So removing the splitter entirely is the
way to go here.
