Akira Hatanaka ea7611b02c Insert llvm_unreachable at the end of a function to silence gcc's
-Werror=return-type error.

This is an attempt to fix the following failing bot:

Akira Hatanaka cae83f78aa [Sema] Issue diagnostics if a new/delete expression generates a call to
a c++17 aligned allocation/deallocation function that is unavailable in
the standard library on Apple platforms.

The aligned functions are implemented only in the following versions or
later versions of the OSes, so clang issues diagnostics if the deployment
target being targeted is older than these:

macosx: 10.13
ios: 11.0
tvos: 11.0
watchos: 4.0

The diagnostics are issued whenever the aligned functions are selected
except when the selected function has a definition in the same file.
If there is a user-defined function available somewhere else, option
-Wno-aligned-allocation-unavailable can be used to silence the
diagnostics.

Alex Lorenz 71d72135b0 Revert r305678: [driver][macOS] Pick the system version for the
deployment target if the SDK is newer than the system

This commit also reverts follow-up commits r305680 and r305685 that have
buildbot fixes.

The change in r305678 wasn't correct because it relied on
`llvm::sys::getProcessTriple`, which uses a pre-configured OS version. We should
lookup the actual macOS version of the system on which the compiler is running.

Alex Lorenz ae9afeb5fa Add missing OS check to r305678
That commit failed on non-macOS buildbots as I've forgotten to make sure that
the system on which Clang is running on is actually macOS.

Alex Lorenz dad1e1a3b5 [driver][macOS] Pick the system version for the deployment target
if the SDK is newer than the system

This commit improves the driver by making sure that it picks the system version
for the deployment target when the version of the macOS SDK is newer than the
system version.

George Karpenkov f2fc5b068e Flag -fsanitize=fuzzer to enable libfuzzer
Previously, adding libfuzzer to a project was a multi-step procedure,
involving libfuzzer compilation, linking the library, and specifying
coverage flags.
With this change,libfuzzer can be enabled by adding a single
-fsanitize=fuzzer flag instead.

Richard Smith ac65f642a5 Update to match LLVM r300135.
Remove "REQUIRES: long_tests" from test/Driver/response-file.c since it is now about 10x faster. (We can add that back if it's still too slow for some buildbot.)

Akira Hatanaka f86ded282d [Driver] Define macro __APPLE_EMBEDDED_SIMULATOR__ when option
-m(i|tv|watch)os-simulator-version-min is on the command line.

Previously the driver would treat -m(i|tv|watch)os-simulator-version-min
as an alias of -m(i|tv|watch)os-version-min. This no longer works since
we now need to distinguish between the two options (the latter is used
for iOS running in a VM, for example).

This commit stops making the simulator options the aliases of the OS
options and defines a macro to differentiate between the two groups of
options.

David L. Jones f561abab56 [Driver] Consolidate tools and toolchains by target platform. (NFC)
Summary:
(This is a move-only refactoring patch. There are no functionality changes.)

This patch splits apart the Clang driver's tool and toolchain implementation
files. Each target platform toolchain is moved to its own file, along with the
closest-related tools. Each target platform toolchain has separate headers and
implementation files, so the hierarchy of classes is unchanged.

There are some remaining shared free functions, mostly from Tools.cpp. Several
of these move to their own architecture-specific files, similar to r296056. Some
of them are only used by a single target platform; since the tools and
toolchains are now together, some helpers now live in a platform-specific file.
The balance are helpers related to manipulating argument lists, so they are now
in a new file pair, CommonArgs.h and .cpp.

I've tried to cluster the code logically, which is fairly straightforward for
most of the target platforms and shared architectures. I think I've made
reasonable choices for these, as well as the various shared helpers; but of
course, I'm happy to hear feedback in the review.

There are some particular things I don't like about this patch, but haven't been
able to find a better overall solution. The first is the proliferation of files:
there are several files that are tiny because the toolchain is not very
different from its base (usually the Gnu tools/toolchain). I think this is
mostly a reflection of the true complexity, though, so it may not be "fixable"
in any reasonable sense. The second thing I don't like are the includes like
"../Something.h". I've avoided this largely by clustering into the current file
structure. However, a few of these includes remain, and in those cases it
doesn't make sense to me to sink an existing file any deeper.
