This adds a new profiling mode for vector instruction shapes. I'm planning on using this to identify any common cases that may be worth special casing, like we do for simple SetM, CGetM, and IssetM instructions. Instead of adding Yet Another Hashtable Stats Map, I created a generic version and changed TRACE=punt:1 to use it as well. I also changed emitInterpOneOrPunt to use a more specific name.
