I have updated the full patch along with the cost model. I have also shared the perf numbers for SPEC CPU 2017 benchmarks in Graviton2 with various modes of optimization enabled : F15848356: function_specialize_spec_2017_graviton2.png <https://reviews.llvm.org/F15848356>

This version of the patch contains the FunctionSpecializer implementation inside SCCP.cpp. It is not dependent on the D93762 <https://reviews.llvm.org/D93762> refactoring of `SCCPSolver` just for review purpose.
