mythria f445f69244 [Crankshaft] Fine tune merging of Ignition and FCG feedback for binary/compare ops. 
Ignition does not collect information about lhs and rhs types. It  collects
information about the combined type of lhs, rhs and result types. Since ignition
combines the feedback, sometimes we may collect less precise information than
FCG. This impacts performance of some benchmarks like audio-beat-detection. This
cl tries to mitigate this affect by passing only full-codegen feedback when the
combined FCG feedback is same as the feedback collected by ignition.
