  [Metarenamer] Introduce option to only change inst names

This is useful when needing to modify IR and test some optimizations on
them, while keeping BB names and function names intact. If
the IR uses ordered number naming (%1, %2, %3 etc), then we cannot just
remove or reorder specific instructions since the verifier expects the
numbers to be in order.
