Andrew Trick d82e0ff781 SILInliner: Critical edges have no code size impact. ...

I think unconditional branches should be free, period. They will
mostly be removed during LLVM code gen. However, fixing this requires
signficant adjustments to inlining heuristics to avoid microbenchmark
regressions at -Osize. So, instead I am just making this less
sensitive to critical edges for the sake of pipeline stability.
