This changes makes GCC asm output use instruction names that are

immediate-operand instructions without the "i" suffix, so this all

When implementing the RISC-V port, I took the name of this macro at
face value. It appears we were mistaken in what this means, here's a
quote from the SPARC port that better describes what SLOW_BYTE_ACCESS
does
/* Nonzero if access to memory by bytes is slow and undesirable.
For RISC chips, it means that access to memory by bytes is no
better than access by words when possible, so grab a whole word
and maybe make use of that. */
I've added the comment to our port as well.
See https://gcc.gnu.org/ml/gcc/2017-08/msg00202.html for more
discussion. Thanks to Michael Clark and Andrew Pinski for the help!

When we are realigning the stack pointer, making an ms_abi to sysv_abi
call and allocating 2GiB or more on the stack we end up with an invalid
INSN due to a non-immediate offset. This occurs both with and without
-mcall-ms2sysv-xlogues. Additionally, the stack allocation with
-mcall-ms2sysv-xlogues is ignoring (silently disabling) stack checking,
stack clash checking and probing.
This patch fixes these problems by:
1. No longer allocate stack space in ix86_emit_outlined_ms2sysv_save.
2. Rearrange where we emit SSE saves or stub call:
a. Before frame allocation when offset from frame to save area is >= 2GiB.
b. After frame allocation when frame is < 2GiB. (Stack allocations
prior to the stub call can't be combined with those afterwards, so
this is better when possible.)
3. Modify choose_baseaddr to take an optional scratch_regno argument
and never return rtx that cannot be used as an immediate.
gcc:
config/i386/i386.c (choose_basereg): Use optional scratch
register and add assertion.
(x86_emit_outlined_ms2sysv_save): Use scratch register when
needed, and don't allocate stack.
