-debug-only option for llc is only available in debug builds so
"REQUIRES: asserts" is needed in the tes.

llvm-svn: 370279
This is a special case because one node maps to two different G_
instructions, and the operand order is changed.

This mostly enables G_FCMP for AMDPGPU. G_ICMP is still manually
selected for now since it has the SALU and VALU complication to deal
with.

llvm-svn: 370280
SGPR spills aren't really handled after SILowerSGPRSpills. In order to
directly control what happens if the scavenger needs to spill, the
scavenger needs to be used directly. There is an alternative to
spilling in these contexts anyway since the frame register can be
increment and restored.

This does present another possible issue if spilling is needed for the
unused carry out if an add is needed. I think this can be avoided by
using a scalar add (although that clobbers SCC, which happens anyway).

When we now verify the iteration count we will see the actual count
and the expected count before the assertion is triggered.

Summary:
This is self-contained, and doesn't need anything in the
compiler to work. Mainly to reduce the diff between upstream
and downstream.

Summary:
The greedy register allocator occasionally decides to insert a large number of
unnecessary copies, see below for an example.  The -consider-local-interval-cost
option (which X86 already enables by default) fixes this.  We enable this option
for AArch64 only after receiving feedback that this change is not beneficial for
PowerPC.

We evaluated the impact of this change on compile time, code size and
performance benchmarks.

This option has a small impact on compile time, measured on CTMark. A 0.1%
geomean regression on -O1 and -O2, and 0.2% geomean for -O3, with at most 0.5%
on individual benchmarks.

The effect on both code size and performance on AArch64 for the LLVM test suite
is nil on the geomean with individual outliers (ignoring short exec_times)
between:

                 best     worst
  size..text     -3.3%    +0.0%
  exec_time      -5.8%    +2.3%

On SPEC CPU® 2017 (compiled for AArch64) there is a minor reduction (-0.2% at
most) in code size on some benchmarks, with a tiny movement (-0.01%) on the
geomean.  Neither intrate nor fprate show any change in performance.

This patch makes the following changes.

- For the AArch64 target, enableAdvancedRASplitCost() now returns true.

- Ensures that -consider-local-interval-cost=false can disable the new
  behaviour if necessary.

This matrix multiply example:

   $ cat test.c
   long A[8][8];
   long B[8][8];
   long C[8][8];

   void run_test() {
     for (int k = 0; k < 8; k++) {
       for (int i = 0; i < 8; i++) {
	 for (int j = 0; j < 8; j++) {
	   C[i][j] += A[i][k] * B[k][j];
	 }
       }
     }
   }

results in the following generated code on AArch64:

  $ clang --target=aarch64-arm-none-eabi -O3 -S test.c -o -

…lvm#68429)

After calling arm_sme_state, the -S assembly would show clang generating
a “tbz xN, #0, Lbb”. However, disassembling it showed that it was
actually encoded as “tbz xN, #32, Lbb”. The issue is that for TBZ, if
you want a bit offset <32 you need to use the W variant, since the
instruction overloads the top bit of the immediate.

This commit breaks coroutine splitting for non-swift calling convention
