We should a bit boost inlining budget for polymorphic calls so that we
can inline some of tiny functions in one site well. This patch adds some
budget based on # of polymorphic call targets. But we are limiting
inlining budget to the default number for each inlining, and we refill
the decreased budget with adjustment after each inlining.
