Add wide_int version of inchash::hash::add_wide_int
This patch adds an inchash hasher for wide_int-based types.
It means that hash_tree no longer hashes TREE_INT_CST_EXT_NUNITS,
but that was redundant with hashing the type.

Rename inchash::hash::add_wide_int
The name inchash::add_wide_int is a bit misleading, since it sounds

Update x86 backend to enable Intel CET.
All platforms except i386 will report the error and do no
instrumentation with -finstrument-control-flow option. i386
will provide the implementation based on a specification
published by Intel for a new technology called Control-flow
Enforcement Technology (CET). The spec is available at
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
The implementation in this patch:
1) enables Control-flow Enforcement Technology (CET), published by
Intel. This part introduces i386 specific options -mcet, -mibt and
-mshstk, new instructions and intrinsics;
2) provides support for -fcf-protection option and 'nocf_check'
attribute by doing needed code instrumentation, which is based on
CET features.

Add generic part for Intel CET enabling. The spec is available at
https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
A proposal is to introduce a target independent flag
-fcf-protection=[none|branch|return|full] with a semantic to
instrument a code to control validness or integrity of control-flow
transfers using jump and call instructions. The main goal is to detect
and block a possible malware execution through transfer the execution
to unknown target address. Implementation could be either software or
target based. Any target platforms can provide their implementation
for instrumentation under this option.
The compiler should instrument any control-flow transfer points in a
program (ex. call/jmp/ret) as well as any landing pads, which are
targets of control-flow transfers.
A new 'nocf_check' attribute is introduced to provide hand tuning
support. The attribute directs the compiler to skip a call to a
function and a function's landing pad from instrumentation. The
attribute can be used for function and pointer to function types,
otherwise it will be ignored.
Currently all platforms except i386 will report the error and do no
instrumentation. i386 will provide the implementation based on a
specification published by Intel for a new technology called
Control-flow Enforcement Technology (CET).

[arm] Fix architecture selection when building libatomic with automatic FPU selection
Libatomic builds a few functions for Arm with an explicit -march
option. This option does not specify an FPU, which can lead to
problems when targeting a hard-float or softfp environment since the
architecture appears to be incompatible with the selected ABI.
The fix is simple enough, just add +fp (the minimum floating point
option) to the architecture. We don't use anything from the FP
architecture, so it shouldn't really change anything; and if we are
building for -mfloat-abi=soft the canonicalization process will remove
the unnecessary fp attributes anyway.

[ARM] PR 82445 - suppress 32-bit aligned ldrd/strd peepholing with -mno-unaligned-access
Peephole patterns exist in the arm backend to spot load/store
operations to adjacent memory operations in order to convert them into
ldrd/strd instructions. However, when we have strict alignment
enforced, then we can only do this if the accesses are known to be
64-bit aligned; this is unlikely to be the case for most loads. The
patch adds some alignment checking to the code that validates the
addresses for use in the peephole patterns. This should also fix
incorrect generation of ldrd/strd with unaligned accesses that could
previously have occurred on ARMv5e where all such operations must be
64-bit aligned.
I've added some new tests as well. In doing so I discovered that the
ldrd/strd peephole tests could never fail since they would match the
source file name in the scanned assembly as well as any instructions
of the intended type. I've fixed those by tightening the scan results
slightly.
