[Bug gcov-profile/32543] New: Gcov: profile.c total_num_edges_instrumented never incremented (patch included)

["hbl at sysgo dot com" <gcc-bugzilla at gcc dot gnu dot org>]

In gcc:profile.c, the variable total_num_edges_instrumented used is initialized
to 0, but never increased. Hence end_branch_prob (which gets called when one
dumps the intermediate *.profile file via the "-fdump-tree-all" option) always
prints "Total number of instrumented edges: 0"  The following patch should fix
this:
