I was thinking about sharing the code between libgcc/gcov/profile.c
somehow for some time too.  It is bit dificult because gcov use
different datastructure for the flowgraph and it is not trivial to
export our CFG code as it is dependent on too many GCC internals, but I
don't see any problem with the profile reading/wrting code and we would
get some goodies for free (like locking of files on compile/gcov reads)
