Per Nick Kledzik (http://llvm.org/bugs/show_bug.cgi?id=17976):
"""
For MacOSX, the labels in __cstring section should be 'L' labels, and the labels
in the __const section should be non-L or 'l' labels. The later ('l') will cause
the linker to remove the label in the final executable.
"""
, so we need to ensure that the globals emitted by ASan have appropriate labels.

This should fix http://llvm.org/bugs/show_bug.cgi?id=17976
Another test checking for the global variables' locations and prefixes on Darwin will be committed separately.

Subsystem field in the PE/COFF file header has no meanining for the DLL.
It looks like MSVC link.exe sets the default subsystem (Windows GUI) to
the field if no /subsystem option is specified.

Even g++ considers this a valid C++ identifier and it should only have been
visible in C mode.
Also drop the associated low-value diagnostic.

...namely LOAD AND ADD, LOAD AND AND, LOAD AND OR and LOAD AND EXCLUSIVE OR.
LOAD AND ADD LOGICAL isn't really separately useful for LLVM.
I'll look at adding reusing the CC results in new year.

This is intended to address the following problem.
Episodically we see CHECK-failures when recursive interceptors call back into user code. Effectively we are not "in_rtl" at this point, but it's very complicated and fragile to properly maintain in_rtl property. Instead get rid of it. It was used mostly for sanity CHECKs, which basically never uncover real problems.
Instead introduce ignore_interceptors flag, which is used in very few narrow places to disable recursive interceptors (e.g. during runtime initialization).

Print the list of leaked objects after each leak report. Previously we
printed only a joint list of all leaked objects. As a bonus, suppressed objects
are no longer reported.

Introduce proper facilities to render token spellings using the diagnostic
formatter.
Replaces most of the hard-coded diagnostic messages related to expected tokens,
which all shared the same semantics but had to be multiply defined due to
variations in token order or quote marks.
The associated parser changes are largely mechanical but they expose
commonality in whole chunks of the parser that can now be factored away.
This commit uses C++11 typed enums along with a speculative legacy fallback
until the transition is complete.
Requires corresponding changes in LLVM r197895.

DAG.getVectorShuffle() doesn't always return a vector_shuffle node.
If mask is the exact sequence of it's operand(For example, operand_0
is v8i8, and the mask is 0, 1, 2, 3, 4, 5, 6, 7), it will directly
return that operand. So a check is added here.
