[PATCH] D65543: Use library basenames when autolinking on Windows

Herald added a project: clang.

Otherwise we embed a potentially absolute and potentially relative path
to clang's resource directory into the object file. Object files with
paths embedded in them are fragile and system specific, even when the
path is relative. They cannot be put in an archive and distributed, for
example.

This will require users to add clang's library directory in its resource
directory to the linker libpath, but that is relatively easy compared to
computing the name of the appropriate compiler-rt library, which is
currently architecture dependent.

This is also consistent with how autolinking seems to work for PS4.
