  AutoUpgrade: Fix assertion on invalid name mangling usage

This was trying to auto-upgrade a read_register call with missing type
mangling. This first would break since getCalledFunction checks the
callee type is consistent, so this would assert there. After that,
the replacement code would die on the type mismatch. Be more
defensive and let the verifier code produce an error that the IR
is broken.
