See what happens if you do a mixed switch/indirect dispatch table. I think
we may stuff all the non-overridable opcodes (flow control, register ops,
stack manipulations, and suchlike things) into the switch as entries with
the rest as indirect calls in the default fallthrough. That'd get us the
faster switch dispatch and still leave the flexibility of indirect functions.
We'd want to build the switch statement programmatically, of course,
otherwise it's too much of a hassle to maintain. (I'm not sure there's
going to be any piece of the core code that hasn't passed through a perl
filter at some point in its life...)
