Fix a trivial instance of CMP0054 that came up on llvmdev.
The other warnings were CMP0057, which is about using the same file as a
MAIN_DEPENDENCY multiple times. The old behavior hasn't been a problem
yet, so I silenced the warning and filed PR23595 to document the issue
if someone cares.

Without the --target flag, clang uses the mips64 triple which selects the n64 abi. We need to add --target=mips-linux-gnu, so that clang can select the correct abi for mips32r2.

Summary:
This will allow us to enable it on the buildbot (and then enable a
sanitizer buildbot).
The problem is that gcc for Mips does not accept -m32/-m64 like clang does.
We therefore need to use the nearest equivalent -mips32r2/-mips64r2. We must
also specify -mabi=64 in the -mips64r2 case since gcc's default ABI has
traditionally been N32 whereas clang's is N64.

Summary:
Change the way we use ASan and UBSan together. Instead of keeping two
separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan
into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on
a platform, all UBSan sources are just compiled into dummy empty object
files. UBSan initialization code (e.g. flag parsing) is directly called
from ASan initialization, so we are able to enforce correct
initialization order.
This mirrors the approach we already use for ASan+LSan. This change
doesn't modify the way we use standalone UBSan.

Passing MSVC-style cflags to the gcc-style clang driver will almost
always end badly. Just translate a couple of simple flags used by the
base CMake cflags like /D, /U, and /O.

This reverts commit r229665. It seems that the AArch64 ASAN tests, that
pass on all our internal machines, doesn't like the public buildbot.
Turning this off until we can investigate the public bot for a better
understanding.

Prior to this change we built two identical runtimes, named "powerpc64"
and "powerpc64le", while their actual endianness matched the host
endianness.

This reverts commit r227966, which turned ASAN on on AArhc64 and may be the
cause of the bots never finishing the check-all. I'll re-apply once we're
sure that bot can cope with it.

This commit changes the strategy for building shared ASan runtime
and the way we test it:
- COMPILER_RT_BUILD_SHARED_ASAN CMake option is removed. We now
always build shared ASan runtime (it is the default on Android,
Windows and Mac, and not the default on Linux and FreeBSD).
- Platforms, which use static runtime by default now have
"check-asan-dynamic" testsuite. This testsuite contains instrumented
unit tests, and ASan lit tests, and runs them with shared ASan
runtime. This testsuite is *not* a part of "check-asan" and
*not* a part of "check-all", as adding 1000 more test cases, which
duplicate existing ones is costly. However, you're welcome to
add this command to your buildbot.

When CMake builds a dynamic library on Windows, the .dll file's location is
determined by the RUNTIME_OUTPUT_DIRECTORY, which we were previously not
setting.
This means for example that clang_rt.asan_dynamic-i386.dll will get built
and installed in the same directory as the corresponding .lib file,
instead of being built in the bin/ directory and not installed at all.

Summary:
I don't know anything about profiling but it seems to work out of the
box on PowerPC64. At least "make check-profile" works.
A few tests needed tweaking because PowerPC64 IR declares main with
"define signext i32 @main" instead of just "define i32 @main".
This also fixes the asan asan_and_llvm_coverage_test test, which
compiles with -coverage so requires that a profiling version of
libclang_rt has been built.
