Summary

When building a precompiled header in -fmodule-format=obj (i.e., `-gmodules) in an absolute path, the locig in CGDebugInfo::createCompileUnit would unconditionally append the source directory to the -main-file-name. This patch avoids that behavior for absolute paths.

Should we check if MainFileDir is absolute to, instead of just checking for .?

We might want to unconditionally call remove-dots instead.
