This patch to the Go frontend adds a location_file method to Linemap,
adding support for getting the file name from a Location value.  This
will be used by later work.  This requires a patch to the interface
between the Go frontend and the rest of GCC.  Bootstrapped and ran Go
testsuite on x86_64-pc-linux-gnu.  Committed to mainline.
