Please don't! The equality operator needs to be based on the same semantics as
the hashing operator. Since the target a handle location can point to can
relocate, which would change the hash, we decided to base both hashing and
equality on the location. This is on purpose.

Okay. I haved fixed the matcher here as the problem was comparing two
CreateClosureParameters instances. The two instances naturally have the same
SharedFunctionInfo objects, but different locations.
