Reviewed by Sam Weinig.

Having introduced the RepatchBuffer, ProcessorReturnAddress is now a do-nothing
wrapper around ReturnAddressPtr. Remove it. In tugging on this piece of string
it made sense to roll out the use of ReturnAddressPtr a little further into
JITStubs (which had always been the intention).

No performance impact.
