This patch fixes PR bootstrap/57077. Certain new uses of apply_probability
are actually scaling the counts up, and the scale factor should not
be treated as a probability as the value may exceed REG_BR_PROB_BASE.
One example (from the PR) is when scaling counts up in LTO when merging
profiles. Another example I found when preparing the patch to use
the rounding divide in more places is when inlining COMDAT functions.
Add new helper function apply_scale that does the scaling without
the probability range check. I audited the new uses of apply_probability
and changed the calls as appropriate.
