cmd/go: don't copy cgo files to objdir when overlay is present The previous cl (golang.org/cl/262618) copied non-overlaid cgo files to objdir, mostly to get around the issue that otherwise cgo-generated files were written out with the wrong names (they'd get the base path of the overlay file containing the replaced contents, instead of the base path of the path whose contents are being replaced). So that CL it would copy the files to objdir with the base path of the file being replaced to circumvent that. This CL changes cmd/go and cmd/cgo so that instead of copying files, it passes the actual path of the file on disk either of the original file (if it is not overlaid) or its replacement file (if it is) as well as a flag --path_rewrite, newly added to cmd/cgo, that specifies the actual original file path that corresponds to the replaced files.
