Kuba Brecka 85e01c0bdc [tsan] Add Clang frontend support for TSan on OS X
We're currently in process of porting TSan to OS X, and quite a few of the initial support in the runtime library has already landed in trunk. This patch actually enables "-fsanitize=thread" in the frontend.

re-applies the original changes but XFAILs the test file which caused
the buildbot failures. This will allow us to examine what's going wrong

John McCall 460ce58fa6 Define weak and __weak to mean ARC-style weak references, even in MRC.
Previously, __weak was silently accepted and ignored in MRC mode.
That makes this a potentially source-breaking change that we have to
roll out cautiously.  Accordingly, for the time being, actual support
for __weak references in MRC is experimental, and the compiler will
reject attempts to actually form such references.  The intent is to
eventually enable the feature by default in all non-GC modes.
(It is, of course, incompatible with ObjC GC's interpretation of
__weak.)

If you like, you can enable this feature with
  -Xclang -fobjc-weak
but like any -Xclang option, this option may be removed at any point,
e.g. if/when it is eventually enabled by default.

This patch also enables the use of the ARC __unsafe_unretained qualifier
in MRC.  Unlike __weak, this is being enabled immediately.  Since
variables are essentially __unsafe_unretained by default in MRC,
the only practical uses are (1) communication and (2) changing the
default behavior of by-value block capture.

As an implementation matter, this means that the ObjC ownership
qualifiers may appear in any ObjC language mode, and so this patch
removes a number of checks for getLangOpts().ObjCAutoRefCount
that were guarding the processing of these qualifiers.  I don't
expect this to be a significant drain on performance; it may even
be faster to just check for these qualifiers directly on a type
(since it's probably in a register anyway) than to do N dependent
loads to grab the LangOptions.

Xinliang David Li 69306c0823 clang driver toolchain refactoring
In this patch, the file static method addProfileRT is
moved to be a virtual member function of base ToolChain class.
This allows derived toolchain to override the default behavior
easily and make it consistent with Darwin toolchain (a TODO was
added for this refactoring - now removed). A new helper method
is also introduced to test if instrumentation profile option
is turned on or not.

Saleem Abdulrasool 436256a713 Support Debug Info path remapping
Add support for the `-fdebug-prefix-map=` option as in GCC.  The syntax is
`-fdebug-prefix-map=OLD=NEW`.  When compiling files from a path beginning with
OLD, change the debug info to indicate the path as start with NEW.  This is
particularly helpful if you are preprocessing in one path and compiling in
another (e.g. for a build cluster with distcc).

Note that the linearity of the implementation is not as terrible as it may seem.
This is normally done once per file with an expectation that the map will be
small (1-2) entries, making this roughly linear in the number of input paths.

Addresses PR24619.
