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. llvm-svn: 239869

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. llvm-svn: 239929
