11898c48c5 Fixed warning: dereferencing type-punned pointer will break strict-aliasing rules. 
No need in reinterpret_cast<StringTableOffset &> here, as struct coff_symbol Name is a unin
with the member StringTableOffset Offset. This union member could be accessed directly.

8147ef1372 Re-land "COFF: migrate def parser from LLD to LLVM" 
This reverts commit r304561 and re-lands r303490 & co.

The fix was to use "SymbolName" when translating LLD's internal export
list to lib/Object's short export struct. The SymbolName reflects the
actual symbol name, which may include fastcall and stdcall mangling bits
not included in the /EXPORT or .def file EXPORTS name:

afe7c5a7a6 Revert "COFF: migrate def parser from LLD to LLVM" 
This reverts commits r303490, r303491, r303493, and r303494.

This caused http://crbug.com/728726. Essentially, exporting stdcall
functions doesn't appear to work after this change. Reduced test case
soon.
