avoid generating drops for moved operands of calls
Currently, after a CALL terminator is created in MIR, we insert DROP statements for all of its operands -- even though they were just moved shortly before! These spurious drops are later removed, but not before causing borrow check errors. This PR series modifies the drop code to track operands that were moved and avoid creating drops for them. Right now, I'm only using this mechanism for calls, but it seems likely it could be used in more places.
