203c90ba80 Convert the archive writer to use Error.
This found one place in lld that was not checking the error.

aa892fdd03 Simplify writeArchive return type.
writeArchive returned a pair, but the first element of the pair is always
its first argument on failure, so it doesn't make sense to return it from
the function. This patch change the return type so that it does't return it.

2c2b0c92d7 [COFF] Make the weak aliases optional
When creating an import library from lld, the cases with
Name != ExtName shouldn't end up as a weak alias, but as a real
export of the new name, which is what actually is exported from
the DLL.

This restores the behaviour of renamed exports to what it was in
4.0.

The other half of this commit, including test, goes into lld.

9c571e9120 [COFF] Add SymbolName as a distinct field in COFFImportFile
The previous Name and ExtName aren't enough to convey all the nuances
between weak aliases and stdcall decorated function names.

A test for this will be added in LLD.

e863b15ae6 [llvm-dlltool] Write correct weak externals
Previously, the created object files for the import library were broken.
Write the symbol table before the string table. Simplify the code by
using a separate variable Prefix instead of duplicating a few lines.

Also update the coff-weak-exports to actually check that the generated
weak symbols can be found as intended.

0b89845991 Object: rename parameter from DLLName to ImportName
When I originally wrote this code, I neglected the fact that the import
library may be created for executables.  This name is not the name of
the DLL, but rather the name for the imported module.  It will be
embedded into the IAT/ILT reference.  Rename it to make it more obvious.

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:

This caused http://crbug.com/728726. Essentially, exporting stdcall
