Previously coverage was computed from the state of ICData at various call-sites in the function. This ties coverage collection with the implementation of various operations. This CL is the first step towards decoupling coverage collection from how individual operations are implemented. We introduce a separate coverage array storing token_pos -> coverage hit mapping. This array is updated by a separate RecordCoverage IL instruction.
