Summary:
This macro is needed to prevent test/CodeGen/Mips/2008-08-01-AsmInline.ll from
failing after the integrated assembler is enabled by default.

When pulling a llvm::Value to be written as a PHI write, the former
code did only check whether it is within the same basic block, but it
could also be the same non-affine subregion. In that case some
unecessary pair of MemoryAccesses would have been created.
Two unit test were explicitely checking for the unecessary writes,
including the comments that the writes are unecessary.

On linux, the environment variables for temp directories that lldb checks for are generally not
defined, and the temp directory computation failed. This caused expression evaluation to fall
back to creating "/tmp/lldb-*.expr" debugging files instead of the usual
"$TMP/lldb/pid/lldb-*.expr". Crucially, these files were not cleaned up on lldb exit, which
caused clutter in the /tmp folder, especially on long-running machines (e.g. builtbots). This
commit fixes lldb to use llvm::sys::path::system_temp_directory, which does the same environment
variable dance, but (!) also falls back to the P_tmpdir macro, which is how the temp directory is
defined on linux.
Since the linux temp path computation now succeeds, I needed to also modify Android path
computation to check for actual directory existence, rather then checking whether the operation
failed.

that is, are misleading in what they actually check.

Summary:
The -mcpu=mips16 option caused the Integrated Assembler to crash because
it couldn't figure out the architecture revision number to write to the
.MIPS.abiflags section. This CPU definition has been removed because, like
microMIPS, MIPS16 is an ASE to a base architecture.

- On mingw-w64, libstdc++-6.dll is used for clang.exe. The DLL might not be in Windows' system directory.
- With --enable-shared, DLLs might be in ${CMAKE_BINARY_DIR}/bin.
I understand this test confirms that appropriate name of executable can be found on %PATH%.
Therefore I added "Output\\" before each expression.
FIXME: The output directory %T is hardcoded like "Output\\ps4-ld.exe".

Rolling this back for now since there are a couple of bot failures on
the new tests I added, and I won't have a chance to look at them in detail
until later this afternoon. I think the new tests need some restrictions on
having the gold plugin available.
This reverts commit r250398.

Summary:
Add clang support for -flto=thin option, which is used to set the
EmitFunctionSummary code gen option on compiles.
Add -flto=full as an alias to the existing -flto.
Add tests to check for proper overriding of -flto variants on the
command line, and convert grep tests to FileCheck.

AVX-512 bit shuffle fails on 32 bit since we create a vector of 64-bit constants.
I split 8x64-bit const vector to 16x32 on 32-bit mode.

When sharing the same map from old to new value, CodeGeneration would
reuse the same new value for each basic block. However, the SCEV
expander might emit code in a basic block that does not dominate a use
of the SCEV in another basic block. This test checks whether both such
blocks have their own expanded new values.

Summary:
I see a lot of following warnings in LLDBWrapPython.cpp while building with gcc 4.9 on Linux.
"warning: cast from type ‘const char*’ to type ‘char*’ casts away qualifiers [-Wcast-qual]"
Is it ok to add -Wno-cast-qual for this file in cmake for gcc. This option seems to be already present
for autotool case.

After some additional post-commit (post-revert) discussion and research, this
reverts, in part, r250205, so the ABI-recommended starting address can be used
on PPC64 (as is done by other linkers).
Also, this addresses the FIXME in ELF/Writer.cpp by making VAStart a
target-dependent property.

failing when the suffix was added.
I assume the lack of a '.s' suffix means that the test case just wasn't running
before, and it has never worked on MIPS. I'll investigate that tomorrow.

(e.g. bss sections).
MachO and ELF have been silently letting this pass, but COFFObjectFile contains
an assertion to catch this kind of (ab)use of the getSectionContents, and this
was causing the JIT to crash on COFF objects with BSS sections. This patch
should fix that.

Recommit r250342: move coal-sections-powerpc.s to subdirectory for powerpc.
Some background on why we don't have to use *coal* sections anymore:
Long ago when C++ was new and "weak" had not been standardized, an attempt was
made in cctools to support C++ inlines that can be coalesced by putting them
into their own section (TEXT/textcoal_nt instead of TEXT/text).
The current macho linker supports the weak-def bit on any symbol to allow it to
be coalesced, but the compiler still puts weak-def functions/data into alternate
section names, which the linker must map back to the base section name.
This patch makes changes that are necessary to prevent the compiler from using
the "coal" sections and have it use the non-coal sections instead when the
target architecture is not powerpc:
TEXT/textcoal_nt instead use TEXT/text
TEXT/const_coal instead use TEXT/const
DATA/datacoal_nt instead use DATA/data
If the target is powerpc, we continue to use the *coal* sections since anyone
targeting powerpc is probably using an old linker that doesn't have support for
the weak-def bits.
Also, have the assembler issue a warning if it encounters a *coal* section in
the assembly file and inform the users to use the non-coal sections instead.
