Teresa Johnson 1e20a652ee [ThinLTO] Appending linkage fixes
Summary:
Fix import from module with appending var, which cannot be imported. The
first fix is to remove an overly-aggressive error check.

The second fix is to deal with restructuring introduced to the module
linker yesterday in r254418 (actually, this fix was included already
in r254559, just added some additional cleanup).

Test by Mehdi Amini.

Nico Weber 08c9333df2 Fix Objective-C metadata for properties from class extensions after r251874
After, properties from class extensions no longer show up in
ObjCInterfaceDecl::properties().  Make ObjCCommonMac::EmitPropertyList()
explicitly look for properties in class extensions before looking at
direct properties.

Also add a test that passes both with clang before r251874 and after this
patch (but fails with r251874 and without this patch).

Marina Yatsina 4b1aea0802 [X86] MS inline asm: produce error when encountering "<type> ptr <reg name>"
Currently "<type> ptr <reg name>" treated as <reg name> in MS inline asm, ignoring the "<type> ptr" completely and possibly ignoring the intention of the user.
Fixed llvm to produce an error when encountering "<type> ptr <reg name>" operands.

For example: andpd xmm1,xmmword ptr xmm1 --> andpd xmm1, xmm1 
though andpd has 2 possible matching formats - andpd xmm, xmm/m128

Kuba Brecka 65aa45e872 [tsan] Use re-exec method to enable interceptors on older versions of OS X
In AddressSanitizer, we have the MaybeReexec method to detect when we're running without DYLD_INSERT_LIBRARIES (in which case interceptors don't work) and re-execute with the environment variable set. On OS X 10.11+, this is no longer necessary, but to have ThreadSanitizer supported on older versions of OS X, let's use the same method as well. This patch moves the implementation from `asan/` into `sanitizer_common/`.

This CL is for discussion how to better fix bit-filed layout compatibility issue with GCC (see PR25575 for test case and more details). Current clang behavior is compatible with GCC 4.1-4.3 series but it was fixed in 4.4+. Ignoring packed attribute looks very odd and because it was also fixed in GCC 4.4+, it makes sense also fix it in clang.

Mehdi Amini 9abe1089c7 Remove "ExportingModule" from ThinLTO Index (NFC)
There is no real reason the index has to have the concept of an
exporting Module. We should be able to have one single unique
instance of the Index, and it should be read-only after creation
for the whole ThinLTO processing.
The linker plugin should be able to process multiple modules (in
parallel or in sequence) with the same index.

The only reason the ExportingModule was present seems to be to
implement hasExportedFunctions() that is used by the Module linker
to decide what to do with the current Module.
For now I replaced it with a query to the map of Modules path to
see if this module was declared in the Index and consider that if
it is the case then it is probably exporting function.
On the long term the Linker interface needs to evolve and this
call should not be needed anymore.
