If ELM could store a bit array and registered events types would be stored in it, testing whether ELM has a listener for certain type might become faster, at least in case there are lots of listeners. Using some tricks the bit array could be perhaps spread to the left-over bits of ListenerStructs. Need to profile.

The answer seems to be that the filter doesn't improve anything but some very artificial tests. Posted to tryserver anyway https://tbpl.mozilla.org/?tree=Try&rev=6971afaf8ba3
