compiler: don't double count "." in nested_function_num

    Nested functions are named "outerfunc.$nestedN", where N is a
    number. nested_function_num extracts that number. The name is
    first passed to unpack_hidden_name, which handles the "." and
    should result "$nestedN". Don't expect the "." again.

[AArch64] Use aarch64_reg_or_imm instead of nonmemory_operand

Some of the shift expanders accepted nonmemory_operands but were only
able to handle register_operands or CONST_INTs.  This is probably
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.

This patch makes the expanders use aarch64_reg_or_imm instead.

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

RISC-V: Set SLOW_BYTE_ACCESS=1

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!

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.

re PR c++/82768 (ICE in synthesize_implicit_template_parm, at cp/parser.c:39338)

Fix PR82768

Forcing LR at the bottom of the frame caused a few test failures.
Since there are some cases that generate worse code, revert this
part, and the frame tests pass again.

Set default sched pressure algorithm

The Arm backend sets the default sched-pressure algorithm to SCHED_PRESSURE_MODEL.
Benchmarking on AArch64 shows this speeds up floating point performance on SPEC -
eg. CactusBSSN improves by ~16%. The gains are mostly due to less spilling,
so enable this on AArch64 by default.

gcc/
* config/aarch64/aarch64.c (aarch64_override_options_internal):
Set PARAM_SCHED_PRESSURE_ALGORITHM to SCHED_PRESSURE_MODEL.
