llvm dev - May 2006 - [LLVMdev] CloneModule ValueMap

After cloning a Module with CloneModule, there doesn't seem to be any
easy way to convert a Value pointing into the old Module to a Value
pointing into the new one.

The CloneModule implementation already has to keep such a mapping
internally, so I've written a patch that exposes it as a second inout
parameter to CloneModule(), with the one param version being a simple
wrapper for backward compatibility.

The type of ValueMap is std::map<const Value *, Value*> and the
semantics are simply:
  Value *New = ValueMap[Old];
