[PECOFF] Handle .drectve section. Summary: The .drectve section contains linker command line options, and the linker is expected to interpret them as if they were given via the command line. In this patch, the command line parser in the driver is called from the object file reader to parse the string. I think this patch is important, because this is the first step towards mutable TargetInfo. We had a discussion about that on llvm-commits mailing list before. I haven't removed "const" from the function signature yet. Instead, I just use cast to remove "const". This is a temporary aid for an experiment. If we don't see any issue with this mutable TargetInfo appraoch, I'll change the function signature, and rename the class LinkerContext from TargetInfo.

# Test if the linker can properly parse the .drectve section contents.
[PECOFF] Add files appear in .drectve to input graph -- so that command line options to specify new input files, such as /defaultlib:foo, is handled properly. Such options were ignored before this patch. llvm-svn: 192342

# "drectve.obj" contains "/defaultlib:vars /subsystem:console,42.195 -?foo"

[PECOFF] Ignore options starting with -? The compiler is allowed to add a linker option starting with -?<name> to .drectve section. If the linker can interpret -<name>, it's processed as if there's no question mark there. If not, such option is silently ignored. This is a COFF's feature to allow the compiler to emit new linker options while keeping compatibility with older linkers. llvm-svn: 189897
