This fixes part of the issue described in PR gcov-profile/54487 where there were warnings about mismatches due to slight differences in the merged histograms in different object files. This can happen due to the truncating integer division in the merge routine, which could result in slightly different histograms when summaries are merged in different orders. 2012-09-07 Teresa Johnson <tejohnson@google.com> PR gcov-profile/54487 * libgcc/libgcov.c (gcov_exit): Avoid warning on histogram differences.

Enhances the gcov program summary by adding a histogram of arc counter entries. This is used to compute working set information in the compiler for use by optimizations that need information on hot vs cold counter values or the rough working set size in terms of the number of counters.
