Also map the personality function in CloneFunctionInto

Also map the personality function in CloneFunctionInto

Summary: The Old personality function gets copied over, but the
Materializer didn't  have a chance to inspect it (e.g. to fix up
references to the correct module for the target function).
Also add a verifier check that makes sure the personality routine
is in the same module as the function whose personality it is.
