Require int32plus for tests that assume so, and conditionally skip pr44024.c,
as it only works if the target allows deletion of null pointer checks.
gcc/testsuite/ChangeLog
* gcc.dg/init-excess-2.c: Require int32plus.
* gcc.dg/pr44024.c: Skip if target keeps null pointer checks.
* gcc.dg/pr59963-2.c: Require int32plus.
* gcc.dg/pr71084.c: Cast pointer to intprt_t.
* gcc.dg/unroll-7.c: Require int32plus.

According to the POWER8 Processor User’s Manual and some
experimentation on power8 hardware, unaligned fp load/store on power8
does not invoke the alignment interrupt.
* config/rs6000/rs6000.h (SLOW_UNALIGNED_ACCESS): Make scalar
float access depend on TARGET_EFFICIENT_UNALIGNED_VSX.
* config/rs6000/rs6000.opt (-mefficient-unaligned-vsx): Renamed
from -mefficient-unaligned-vector. Note that this affects fp too.

C++ code to using {}'s.

instructions and avoid multiple writes to SP. The key idea is that epilogs
are almost exact reverses of prologs, and thus all the decisions only need
to be taken once. The frame layout is decided in aarch64_layout_frame()
and decisions recorded in the new aarch64_frame fields initial_adjust,
callee_adjust, callee_offset and final_adjust.
A generic frame setup consists of 5 basic steps:
1. sub sp, sp, initial_adjust
2. stp reg1, reg2, [sp, -callee_adjust]! (push if callee_adjust != 0)
3. add fp, sp, callee_offset (if frame_pointer_needed)
4. stp reg3, reg4, [sp, callee_offset + N*16] (store remaining callee-saves)
5. sub sp, sp, final_adjust
The epilog reverses this, and may omit step 3 if alloca wasn't used.
gcc/
* config/aarch64/aarch64.h (aarch64_frame):
Remove padding0 and hardfp_offset. Add locals_offset,
initial_adjust, callee_adjust, callee_offset and final_adjust.
* config/aarch64/aarch64.c (aarch64_layout_frame):
Remove unused padding0 and hardfp_offset initializations.
Choose frame layout and set frame variables accordingly.

TImode register referenced in debug insn can be converted to V1TImode by
scalar to vector optimization. When converting a TImode store to V1TImode,
we need to check all debug insns on its use chain to convert the V1TImode
register to SUBREG TImode if source register is undefined.
