This refactoring 
* Moves the threshold computation methods to InlineCost.cpp. 
* Removes state related to Threshold from the base Inliner class and moves it to SimpleInliner since threshold is only relevant for ICA which is used by SimpleInliner.
* Cleans up getInlineThreshold a little bit.

NFC intended. The motivation for this refactor is to allow getInlineThreshold to be called from inside CallAnalyzer when peering through indirect calls instead of using a constant value.
