This change turns -fsanitize-memory-track-origins into
-fsanitize-memory-track-origins=[level] flag (keeping the old one for
compatibility). Possible levels are 0 (off), 1 (default) and 2 (incredibly
detailed). See docs (part of this patch) for more info.

This is because the PCH is tied to the module files, if one of the module files changes or gets removed
the build system should re-build the PCH file.

that implicitly converts to 'bool' (such as pointers, and the first operand of
?:). Clean up issues found by this. Patch by Stephan Tolksdorf!

When enabled, always validate the system headers when loading a module.
The end result of this is that when these headers change, we will notice
and rebuild the module.

line arguments and directories tree. The old toolchain selection heuristics
worked incorrectly when user has a reduced MIPS toolchain supports
the O32 ABI only.

a missing include from CLog.h.
CLog.h referenced most of the core libclang types but never directly
included Index.h that provides them. Previously it got lucky and other
headers were always included first but with the sorting it ended up
first in one case and stopped compiling. Adding the Index.h include
fixes it right up.

Generating RTTI in the MS ABI is currently not supported, and the failures
are confusing to users, so let's disable it by default for now.

The integrated assembler is a feature. This makes the new flags the default
option, and the previous versions aliases. Ideally, at some point the aliases
would be entirely removed.

Forward the -no-integrated-as option to -cc1 rather than simply invoking the
appropriate tool. This is useful since this option has been overloaded to
permit disabling of parsing inline assembly at the MC layer.
This re-applies the previous version of the patch with a renaming of the driver
option to the public name rather than the internal name (-target vs -triple).
The actual failure is fixed separately of an overly aggressive negative pattern
match in the MIPS driver tests. It also fixes the incorrect test for targets
that have the integrated assembler disabled by default.

Added two new options for -mfpu when targetting ARM:
* fpv4-sp-d16
* fp4-sp-d16
The first is the same spelling as gcc.
The lack of a leading `v' is correct, this is consistent with ARM's
documentation and gcc's spelling of the option.

This does;
- clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
- List of targets is added to LLVM_COMMON_DEPENDS.
- all clang libraries and targets depend on generated headers.
You might wonder this would be regression, but in fact, this is little loss.
- Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
- clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
- Each library's dependencies to tblgen'd files might vary along headers' structure.
It made hard to track and update *really optimal* dependencies.
Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

There is no bound architecture for the dsymutil action in the driver. Trying
to check various properties of the target will cause an assertion failure
because the target doesn't get initialized without a bound architecture.
