Performance numbers.

Sunspider pre-patch: ~1625ms
Patching all but nodes.cpp: ~1630ms (adding new opcodes to Machine seem to
cause a performance hit – saw the same thing trying to add an op_sample. :-/ )
Patching all: ~1645ms

Puzzling.  From profiling the change seems to be operating as expected – best
guess, this is handled well anyway with the fast case at the top of
op_get_by_val, and the increased code footprint results in the degradation?
