[PATCH] gcov: fix file and function summary information

["Martin Liška" <mliska@suse.cz>]

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Jorgen: Can you please test it before I'll install it?

Thanks,
Martin

gcc/ChangeLog:

	* gcov.cc (add_line_counts): Add group functions to coverage
	summary.
	(accumulate_line_counts): Similarly for files.
