  Log Message:
  -----------
  [InlineCost] model calls to llvm.objectsize.*

Very similar to https://reviews.llvm.org/D111272. We very often can
evaluate calls to llvm.objectsize.* regardless of inlining. Don't count
calls to llvm.objectsize.* against the InlineCost when we can evaluate
the call to a constant.
