InlineCostCallAnalyzer encourages inlining of the last call to the
static function by subtracting LastCallToStaticBonus from Cost.

This patch introduces getLastCallToStaticBonusApplied to make
available the amount of LastCallToStaticBonus applied.

The intent is to allow the module inliner to determine whether
inlining a given call site is expected to reduce the caller size with
an expression like:

  IC.getCost() + IC.getLastCallToStaticBonusApplied() < 0

This patch does not add a use of getLastCallToStaticBonus yet.
