[PATCH][LTO] Fix some guality

[Richard Guenther]

This outputs the function start and end loci which allows breaking on
the lines the guality tries to.

Bootstrap and regtest running on x86_64-unknown-linux-gnu, will apply
once that succeeded.

Richard.

	* lto-streamer-out.c (output_function): Output function
	start and end loci.
	* lto-streamer-in.c (input_function): Input function start
	and end loci.
