Implement N disk counters for single value and indirect call counters.
2019-06-10 Martin Liska <mliska@suse.cz>
* gcov-io.h (GCOV_DISK_SINGLE_VALUES): New.
(GCOV_SINGLE_VALUE_COUNTERS): Likewise.
* ipa-profile.c (ipa_profile_generate_summary):
Use get_most_common_single_value.
* tree-profile.c (gimple_init_gcov_profiler):
Instrument with __gcov_one_value_profiler_v2
and __gcov_indirect_call_profiler_v4.
* value-prof.c (dump_histogram_value):
Print all values for HIST_TYPE_SINGLE_VALUE.
(stream_out_histogram_value): Update assert for
N values.
(stream_in_histogram_value): Set number of
counters for HIST_TYPE_SINGLE_VALUE.
(get_most_common_single_value): New.
(gimple_divmod_fixed_value_transform):
Use get_most_common_single_value.
(gimple_ic_transform): Likewise.
(gimple_stringops_transform): Likewise.
(gimple_find_values_to_profile): Set number
of counters for HIST_TYPE_SINGLE_VALUE.
* value-prof.h (get_most_common_single_value):
New.
2019-06-10 Martin Liska <mliska@suse.cz>
* Makefile.in: Add __gcov_one_value_profiler_v2,
__gcov_one_value_profiler_v2_atomic and

* libgcov-merge.c (__gcov_merge_single): Change
function signature.
(merge_single_value_set): New.
* libgcov-profiler.c (__gcov_one_value_profiler_body):
Update functionality.
