Log:
Revised patch to ensure that histograms from the profile summary are streamed
through the LTO files so that the working set can be computed for use in
downstream optimizations.

	* lto-cgraph.c (output_profile_summary): Stream out sum_all
	and histogram.
	(input_profile_summary): Stream in sum_all and histogram.
	(merge_profile_summaries): Merge sum_all and histogram, and
	change to use RDIV.
	(input_symtab): Call compute_working_sets after merging
	summaries.
	* gcov-io.c (gcov_histo_index): Make extern for compiler.
	* gcov-io.h (gcov_histo_index): Ditto.
	* profile.c (compute_working_sets): Remove static keyword.
	* profile.h (compute_working_sets): Ditto.
