It turned out to be a trivial change to support profiled castclass as an addition to profiled isinst.

To move non-profiled casts I will have to add a few additional things:

  1. In some cases we don't need the fallback call at all, e.g. obj is string because string is sealed
  2. In some cases the fallback call should be marked as no-return (and its block converted to BBJ_THROW)
  3. getExactClasses for NativeAOT
    ...
