Rui Ueyama 1f373704e3 COFF: Support module-definition files.
Module-definition files (.def files) are yet another way to
specify parameters to the linker. You can write a list of dllexported
symbols in module-definition files instead of using /export command
line option. It also supports a few more directives.

The parser code is taken from lib/Driver/WinLinkModuleDef.cpp
with the following modifications.

 - variable names are updated to comply with the LLVM coding style.
 - Instead of returning parsing results as "directive" objects,
   it updates Config object directly.

Rui Ueyama 97dff9ee3a COFF: Support creating DLLs.
DLL files are in the same format as executables but they have export tables.
The format of the export table is described in PE/COFF spec section 5.3.

A new class, EdataContents, takes care of creating chunks for export tables.
What we need to do is to parse command line flags for dllexports, and then
instantiate the class to create chunks. For the writer, export table chunks
are opaque data -- it just add chunks to .edata section.
