Inliner: allow replay log to override force inlines

Inliner: allow replay log to override force inlines

ReplayPolicy only impacts discretionary inlines, so could not control
force inline candidates. This has lead to some confusion during inline
studies.

Since most cases of force inline are performance related, allow replay
to override and control these force inline candidates.

This might be useful down the road to study how likely it is that a force
inline directive is either unnecessary or perhaps even detremental to
performance.
