Remove wrong assert about gcov_type (PR lto/79587).
2017-02-22 Martin Liska <mliska@suse.cz>
PR lto/79587
* data-streamer-in.c (streamer_read_gcov_count): Remove assert.
* data-streamer-out.c (streamer_write_gcov_count_stream):
Likewise.
* value-prof.c (stream_out_histogram_value): Make assert more
precise based on type of counter.
