rs6000: Use isel for the cstore patterns

We currently generate (sometimes pretty long) sequences of integer
insns to implement the various cstore patterns.  If the CPU has a fast
isel, we can use that at the same latency as of just two integer insns

but those are not in the critical path: they don't depend on any other
instruction).

There are a few patterns that already are implemented with just two
instructions; so don't use isel in that case (I still need to check
all lt/gt/ltu/gtu/le/leu/ge/geu patterns with all SI/DI combinations,
one or two might be better without isel).

Some of the shift expanders accepted nonmemory_operands but were only

academic without SVE, since we're not likely to see shifts by other
types of constant (const_wide_ints, consts, etc).  But for SVE,
it's possible for a vectorised shift induction to have a CONST_POLY_INT
shift amount.

FT32 makes use of multiple address spaces.

FT32 makes use of multiple address spaces. When trying to inspect
objects in GDB, GDB was treating them as a straight "const". The cause
seems to be in GCC DWARF2 output.

This output is handled in gcc/gcc/dwarf2out.c, where modified_type_die()
checks that TYPE has qualifiers CV_QUALS. However while TYPE has
ADDR_SPACE qualifiers, the modified_type_die() explicitly discards the
ADDR_SPACE qualifiers.

This patch retains the ADDR_SPACE qualifiers as modified_type_die()
outputs the DWARF type tree.  This allows the types to match, and correct
type information for the object is emitted.

PR82816: Widening multiplies of bitfields

In this PR we tried to create a widening multiply of two 3-bit numbers,
but that isn't a widening multiply at the optab/rtl level, since both
the input and output still have the same mode.

We could trap this either in is_widening_mult_p or (as the patch does)
in the routines that actually ask for an optab.  The latter seemed
more natural since is_widening_mult_p doesn't otherwise care about modes.

This changes makes GCC asm output use instruction names that are

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

PR target/82002 Part 2: Correct non-immediate offset/invalid INSN

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.
(ix86_expand_prologue): Rearrange where SSE saves/stub call is
emitted, correct wrong allocation with -mcall-ms2sysv-xlogues.
(ix86_emit_outlined_ms2sysv_restore): Fix non-immediate offsets.
