First phase of unifying the computation of profile scale factors/probabilities and the actual scaling to use rounding divides...

First phase of unifying the computation of profile scale factors/probabilities
and the actual scaling to use rounding divides:
- Add new macro GCOV_COMPUTE_SCALE to basic-block.h to compute the scale
factor/probability via a rounding divide.
- Change all locations that already perform rounding divides (inline or via RDIV)
to use the appropriate helper: GCOV_COMPUTE_SCALE, apply_probability or
combine_probabilities.
- Change ipa-cp.c truncating divides to use rounding divides.
- Add comments to all other locations (currently using truncating divides) to
switch them to one of the helpers so they use a rounding divide.

Next phase will be to replace the locations using truncating divides, marked
with a comment here, into rounding divides via the helper methods.
