Explicitly selected MIPS ABI using the `-mabi` option implies
corresponding target triple. For 'O32' ABI it's a 32-bit target triple
like `mips-linux-gnu`. For 'N32' and 'N64' ABIs it's a 64-bit target
triple like `mips64-linux-gnu`. This patch adjusts target triple
accordingly these rules like we do for pseudo-target flags '-m64',
'-m32' etc already.

With clang-cl, when the user specifies /Yc or /Yu without a filename
the compiler uses a #pragma hdrstop in the main source file to
determine the end of the PCH. If a header is specified with /Yc or
/Yu #pragma hdrstop has no effect.
The optional #pragma hdrstop filename argument is not yet supported.

Implement support for MS-style PCH through headers.
This enables support for /Yc and /Yu where the through header is either
on the command line or included in the source. It replaces the current
support the requires the header also be specified with /FI.
This change adds a -cc1 option -pch-through-header that is used to either
start or stop compilation during PCH create or use.
When creating a PCH, the compilation ends after compilation of the through
header.
When using a PCH, tokens are skipped until after the through header is seen.

With MSVC, PCH files are created along with an object file that needs to
be linked into the final library or executable. That object file
contains the code generated when building the headers. In particular, it
will include definitions of inline dllexport functions, and because they
are emitted in this object file, other files using the PCH do not need
to emit them. See the bug for an example.
This patch makes clang-cl match MSVC's behaviour in this regard, causing
significant compile-time savings when building dlls using precompiled
headers.
For example, in a 64-bit optimized shared library build of Chromium with
PCH, it reduces the binary size and compile time of
stroke_opacity_custom.obj from 9315564 bytes to 3659629 bytes and 14.6
to 6.63 s. The wall-clock time of building blink_core.dll goes from
38m41s to 22m33s. ("user" time goes from 1979m to 1142m).

This code was introduced back in r178148, a change to introduce
-module-file-info - which still exists & seems like it's still tested (&
this change didn't cause any of those tests to fail).
It doesn't look like this change was necessary there - since it's about
pcm output, whereas -module-file-info looks like it's for pcm /input/.
So I'm not really sure what the original motivation was.
I'm open to ideas though, if it turns out the original change was
necessary/useful.

This breaks the OpenFlags enumeration into two separate
enumerations: OpenFlags and CreationDisposition. The first
controls the behavior of the API depending on whether or not
the target file already exists, and is not a flags-based
enum. The second controls more flags-like values.
This yields a more easy to understand API, while also allowing
flags to be passed to the openForRead api, where most of the
values didn't make sense before. This also makes the apis more
testable as it becomes easy to enumerate all the configurations
which make sense, so I've added many new tests to exercise all
the different values.

HIP uses clang-offload-bundler to bundle intermediate files for host
and different gpu archs together. When a file is unbundled,
clang-offload-bundler should be called only once, and the objects
for host and different gpu archs should be passed to the next
jobs. This is because Driver maintains CachedResults which maps
triple-arch string to output files for each job.
This patch fixes a bug in Driver::BuildJobsForActionNoCache which
uses incorrect key for CachedResults for HIP which causes
clang-offload-bundler being called mutiple times and incorrect
output files being used.
It only affects HIP.

Summary:
In rL327851 the createUniqueFile() and createTemporaryFile()
variants that do not return the file descriptors were changed to
create empty files, rather than only check if the paths are free.
This change was done in order to make the functions race-free.
That change led to clang-tidy (and possibly other tools) leaving
behind temporary assembly files, of the form placeholder-*, when
using a target that does not support the internal assembler.
The temporary files are created when building the Compilation
object in stripPositionalArgs(), as a part of creating the
compilation database for the arguments after the double-dash. The
files are created by Driver::GetNamedOutputPath().
Fix this issue by cleaning out temporary files at the deletion of
Compilation objects.
This fixes https://bugs.llvm.org/show_bug.cgi?id=37091.

If -no-canonical-prefixes isn't used, the clang executable name used
is the one of the actual executable, not the name of the symlink that
the user invoked.
In these cases, the target prefix was overridden based on the clang
executable name. (On the other hand the implicit -target option
that such a symlink adds, is added as an actual command line parameter
in tools/driver/driver.cop, before resolving the symlink and finding
the actual clang executable.
Use the original ClangNameParts (set from argv[0] in
tools/driver/driver.cpp) if it seems to be initialized propery.
All existing tests of this feature used -no-canonical-prefixes
(possibly because it also makes the driver look in the directory
of the symlink instead of the directory of the executable); add
another one that uses --config-user-dir= to specify the directory
instead. (For actual users of such symlinks, outisde of the test
suite, the directory is probably the same for both.)
This makes this feature work more like what the documentation
describes.

Summary:
The clang driver option -save-temps was not passed to the LTO config,
so when invoking the ThinLTO backends via clang during distributed
builds there was no way to get LTO to save temp files.
Getting this to work with ThinLTO distributed builds also required
changing the driver to avoid a separate compile step to emit unoptimized
bitcode when the input was already bitcode under -save-temps. Not only is
this unnecessary in general, it is problematic for ThinLTO backends since
the temporary bitcode file to the backend would not match the module path
in the combined index, leading to incorrect ThinLTO backend index-based
optimizations.

-cc1gen-reproducer driver option
The recommit fixes:
- An MSAN failure (CCPrintOptions wasn't initialized in the Driver)
- Ensures that the strings in the libclang invocation files are escaped
Original message:
This commit is a follow up to the previous work that recorded Libclang invocations
into temporary files: r319702.
It adds a new -cc1 mode to clang: -cc1gen-reproducer. The goal of this mode is to generate
Clang reproducer files for Libclang tool invocation. The JSON format in the invocation
files is not really intended to be stable, so Libclang and Clang should be of the same version
when generating reproducers.
The new mode emits the information about the temporary files and Libclang-specific information
to stdout using JSON.

This fixes host-side LTO during CUDA compilation. Before, LTO
pipeline construction was clashing with CUDA pipeline construction.
At the moment there's no point doing LTO on device side as each

compilation pipeline construction for the device-side LTO when we
have working support for multi-TU device-side CUDA compilation.

Previously, we passed "#" to --autocomplete to indicate to enable cc1
flags. For example, when -cc1 or -Xclang was passed to bash, bash
executed `clang --autocomplete=#-<flag they want to complete>`.
However, this was not a good implementation because it depends -Xclang
and -cc1 parsing to shell. So I changed this to pass all flags shell
has, so that Clang can handle them internally.
I had to change many testcases because API spec changed quite a lot.
