Summary: This patch avoids an assert in IPConstantPropagation when there is a argument count/type mismatch between the caller and the callee. While this is actually UB on C-level (clang emits a warning), the IR verifier seems to accept it. I'm not sure what other frontends/languages might think about this, so simply bailing out to avoid hitting an assert (in CallSiteBase<>::getArgOperand or Value::doRAUW) seems like a simple solution. The problem is exposed by the fact that AbstractCallSites will look through a bitcast at the callee position of a call/invoke.
