Detailed Description

Correctly update FunctionPropertiesInfo post-inlining.

A FunctionPropertiesUpdater keeps the state necessary for tracking the changes llvm::InlineFunction makes. The idea is that inlining will at most modify a few BBs of the Caller (maybe the entry BB and definitely the callsite BB) and potentially affect exception handling BBs in the case of invoke inlining.
