Dan Gohman 5fa417c790 Fix memdep's code for reasoning about dependences between two calls. A Ref ...

response from getModRefInfo is not useful here. Instead, check for identical
calls only in the NoModRef case.

Reapply r110270, and strengthen it to compensate for the memdep changes.
When both calls are readonly, there is no dependence between them.
