I am really sorry for the noise, but the current state where some parts of the
code use TD (from the old name: TargetData) and other parts use DL makes it
hard to write a patch that changes where those variables come from and how
they are passed along.

should not be marked nounwind.

Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable 
sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind 
data for that matter), making deoptimization via stackmaps impossible.

This changes the stackmap intrinsic to be may-throw, adds a test for exactly the 
sympton that WebKit saw, and fixes TableGen to handle un-attributed intrinsics.

Thanks to atrick and philipreames for reviewing this.

Sema: Do not assert when dereferencing member pointer using virtual inheritance with an incomplete class type

The MS ABI requires that we determine the vbptr offset if have a
virtual inheritance model.  Instead, raise an error pointing to the
diagnostic when this happens.

This fixes PR18583.

gcc never expands macros in pragmas and MSVC always expands macros
before processing pragmas.  Clang usually allows macro expansion, except
in a handful of pragmas, most of which are handled by the lexer.

Also remove PPCallbacks for pragmas that are currently handled in the
parser.  Without a Parser, such as with clang -E, these callbacks would
never be called.

Fixes PR18576.

This reduces the number of files we need to touch to add a new pragma,
and reduces the number of externally visible symbols in clang.

Make the handlers structs instead of classes because the vast majority
have no private members.

The SuppressWarnings flag, unfortunately, isn't very useful for custom tools
that want to use the LLVM module linker. So I'm changing it to a parameter of
the Linker, and the flag itself moves to the llvm-link tool.

For the time being as SuppressWarnings is pretty much the only "option" it
seems reasonable to propagate it to Linker objects. If we end up with more
options in the future, some sort of "struct collecting options" may be a
better idea.

Previously reverted in r201755 due to causing an assertion failure.

I've removed the offending assertion, and taught the CompilerInstance to
create a default virtual file system inside createFileManager. In the
future, we should be able to reach into the CompilerInvocation to
customize this behaviour without breaking clients that don't care.

This pass eliminates loop iterations that compute results that are not used
later on. This can help e.g. in D, where the default zero-initialization is
often unnecessary if right after new values are assigned to an array.

We do not have a use for this information at the moment. If we need this at some
point, the "instruction -> access" mapping needs to be enhanced as a single
instruction could then possibly perform multiple accesses.

This patch allows us to build the polyhedral information for scops with scalar
dependences.

When CLANG_BUILD_EXAMPLES is not on we set the EXCLUDE_FROM_ALL
directory property for the examples/ directory to tell CMake not to
build them by default.  The AddLLVM.cmake APIs are not aware of this and
try to install targets that are not built.  This does not cause an
install-time error because CMake excludes the directory from the default
installation.  However, now that installation attaches targets to the
LLVMExports export set CMake-based applications that find_package(LLVM)
fail because the example plugin binary is not available.

Tell the AddLLVM.cmake APIs to exclude the examples from installation by
setting the EXCLUDE_FROM_ALL variable they check.

Summary:
This removes the need to coerce UnknownABI to the default ABI (O32 for
MIPS32, N64 for MIPS64 [*]) in both MipsSubtarget and MipsAsmParser.

Clang has been updated to disable both possible default ABI's before enabling
the ABI it intends to use.

[*] N64 being the default for MIPS64 is not actually correct.
    However N32 is not fully implemented/tested yet.
