PR80131: Simplification of 1U << (31 - x)

Currently the code A << (B - C) is not simplified.
However at least a more specific case of 1U << (C -x) where
C = precision(type) - 1 can be simplified to (1 << C) >> x.

This is done by adding a new simplification rule in match.pd.

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.

[AArch64] Add an endian_lane_rtx helper routine

Later patches turn the number of vector units into a poly_int.
We deliberately don't support applying GEN_INT to those (except
in target code that doesn't distinguish between poly_ints and normal
constants); gen_int_mode needs to be used instead.

This patch therefore replaces instances of:

  GEN_INT (ENDIAN_LANE_N (builtin_mode, INTVAL (op[opc])))

with uses of a new endian_lane_rtx function.

[Arm] Cleanup IT attributes

latent issue, change the default of predicable_short_it to "no" so that only

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.

RISC-V: Emit "i" suffix for instructions with immediate operands

This changes makes GCC asm output use instruction names that are

closely.

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.
(ix86_emit_outlined_ms2sysv_restore): Fix non-immediate offsets.

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.

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

rs6000: Improve *lt0 patterns

The rs6000 port currently has an *lt0_disi define_insn, setting the DI
result to whether the SI argument is negative or not. It turns out the
generic optimisers cannot always figure out in the other cases either
that this is just a shift for us. This patch adds patterns for all
four SI/DI combinations.

PR82809: register handling in ix86_vector_duplicate_value

When adding the call to gen_vec_duplicate, I failed to notice that
code further down modified the VEC_DUPLICATE in place. That isn't
safe if gen_vec_duplicate returned a const_vector.

combine: Print insns we try to combine

This adds some extra debug info to the dump file for combine: print
the insns that are input to try_combine. I was worried printing more
will make the dump file only harder to read, but especially the info
from the REG_DEAD notes is invaluable.
