Title: Allow JIT optimization.

Firefox speeds up a lot with this. Fixes the speed part of #19 -- still too slow, probably has to do with Firefox's timing apis. (Firefox no longer eats an entire core after this.)

The reason this works is that the JIT no longer has to run a check every time it loops, as "+0" marks the value as an integer.
