d3a38ccfbb Fix a theoretical problem (not seen in the wild): if different instances of a 
weak variable are compiled by different compilers, such as GCC and LLVM, while
LLVM may increase the alignment to the preferred alignment there is no reason to
think that GCC will use anything more than the ABI alignment.  Since it is the
GCC version that might end up in the final program (as the linkage is weak), it
is wrong to increase the alignment of loads from the global up to the preferred
alignment as the alignment might only be the ABI alignment.

Increasing alignment up to the ABI alignment might be OK, but I'm not totally
convinced that it is.  It seems better to just leave the alignment of weak
globals alone.

116bc795da MC/X86/COFF: Allow quotes in names when targeting MS/Windows, 
as MC is the only assembler we support.

This splits MS/Windows and GNU/Windows ASM infos into two seperate classes.
While there is currently only one difference, full MS C++ ABI support will
require many more.

b0436a7305 Fixed ObjectFile functions: 
- getSymbolOffset() renamed as getSymbolFileOffset()
- getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile.
- added getRelocationOffset()
- fixed MachOObjectFile::getSymbolSize()
- fixed MachOObjectFile::getSymbolSection()
- fixed MachOObjectFile::getSymbolOffset() for symbols without section data.

d7c2494b3c On MachO, the pointer to the personality function should always be in the 
non_lazy_symbol_pointers section (__IMPORT,__pointers). Ignore the 'hidden' part
since that will place it in the wrong section.

cc966de237 Add a link from the LLVM release notes to the Clang release notes. 
I suspect we could profitably remove/move some of the bullet points
under Clang here to the Clang notes in order to keep things clean on
both sides. Unless I hear objections I'll start doing that once folks
have read over the Clang notes a bit.

ed1c0c7f58 Revert r145273 and fix in SelectionDAG::InferPtrAlignment() instead. 
Conservatively returns zero when the GV does not specify an alignment nor is it
initialized. Previously it returns ABI alignment for type of the GV. However, if
the type is a "packed" type, then the under-specified alignments is attached to
the load / store instructions. In that case, the alignment of the type cannot be
trusted.
