Summary:
This patch simply adds support for the new CPU in anticipation of
Power10. There isn't really any functionality added so there are no
associated test cases at this time.

In D49466, sys::path::replace_path_prefix was used instead startswith for -f[macro/debug/file]-prefix-map options.
However those were reverted later (commit rG3bb24bf25767ef5bbcef958b484e7a06d8689204) due to broken Windows tests.
This patch restores those replace_path_prefix calls.
It also modifies the prefix matching to be case-insensitive under Windows.

https://gcc.gnu.org/legacy-ml/gcc-patches/2019-11/msg02647.html
In detail this patch
- march options for armv8.6-a
- BFloat16 assembly
This is part of a patch series, starting with command-line and Bfloat16
assembly support. The subsequent patches will upstream intrinsics
support for BFloat16, followed by Matrix Multiplication and the
remaining Virtualization features of the armv8.6-a architecture.

Summary:
This patch implements feature test macros for the CDE extension
according to the upcoming ACLE specification.
The following 2 macros are being added:
- __ARM_FEATURE_CDE - defined as '1' when any coprocessor is
configured as a CDE coprocessor
- __ARM_FEATURE_CDE_COPROC - defined as an 8-bit mask, each bit of the
mask corresponds to a coprocessor and is set when the corresponding
coprocessor is configured as CDE (and cleared otherwise).
The patch also exposes the value of __ARM_FEATURE_CDE_COPROC in the
target-independent method TargetInfo::getARMCDECorpocMask, the method
will be used in follow-up patches implementing semantic checks of CDE
intrinsics (we want to diagnose the cases when CDE intrinsics are used
with coprocessors that are not configured as CDE).

Summary:
User can select the version of SYCL the compiler will
use via the flag -sycl-std, similar to -cl-std.
The flag defines the LangOpts.SYCLVersion option to the
version of SYCL. The default value is undefined.
If driver is building SYCL code, flag is set to the default SYCL
version (1.2.1)
The preprocessor uses this variable to define CL_SYCL_LANGUAGE_VERSION macro,
which should be defined according to SYCL 1.2.1 standard.
Only valid value at this point for the flag is 1.2.1.

This flag is like /showIncludes, but it only includes user headers and
omits system headers (similar to MD and MMD). The motivation is that
projects that already track system includes though other means can use
this flag to get consistent behavior on Windows and non-Windows, and it
saves tools that output /showIncludes output (e.g. ninja) some work.
implementation-wise, this makes `HeaderIncludesCallback` honor the
existing `IncludeSystemHeaders` bit, and changes the three clients of
`HeaderIncludesCallback` (`/showIncludes`, `-H`, `CC_PRINT_HEADERS=1`)
to pass `-sys-header-deps` to set that bit -- except for
`/showIncludes:user`, which doesn't pass it.

WG21 considers the C++20 standard to be finished (even though it still
has some more steps to pass through in the ISO process).
The old flag names are accepted for compatibility, as usual, and we
still have lots of references to C++2a in comments and identifiers;
those can be cleaned up separately.

Summary:
- The device compilation needs to have a consistent source code compared
to the corresponding host compilation. If macros based on the
host-specific target processor is not properly populated, the device
compilation may fail due to the inconsistent source after the
preprocessor. So far, only the host triple is used to build the
macros. If a detailed host CPU target or certain features are
specified, macros derived from them won't be populated properly, e.g.
`__SSE3__` won't be added unless `+sse3` feature is present. On
Windows compilation compatible with MSVC, that missing macros result
in that intrinsics are not included and cause device compilation
failure on the host-side source.
- This patch addresses this issue by introducing two `cc1` options,
i.e., `-aux-target-cpu` and `-aux-target-feature`. If a specific host
CPU target or certain features are specified, the compiler driver will
append them during the construction of the offline compilation
actions. Then, the toolchain in `cc1` phase will populate macros
accordingly.
- An internal option `--gpu-use-aux-triple-only` is added to fall back
the original behavior to help diagnosing potential issues from the new
behavior.

Since 2009 (in r63846) we've been `#define`-ing OBJC_NEW_PROPERTIES all
the time on Darwin, but this macro only makes sense for `-x objective-c`
and `-x objective-c++`. Restrict it to those cases (for which there is
already separate logic).

Summary:
This adds the reference types target feature. This does not enable any
more functionality in LLVM/clang for now, but this is necessary to embed
the info in the target features section, which is used by Binaryen and
Emscripten. It turned out that after D69832 `-fwasm-exceptions` crashed
because we didn't have the reference types target feature.
