Mircea Trofin cb0c00be5f [llvm] Add interface to drive inlining decision using ML model 
Summary:

This change introduces InliningAdvisor (and related APIs), the interface
that abstracts decision making away from the inlining pass. We will use
this interface to delegate decision making to a trained ML model,
subsequently (see referenced RFC).
