can and does

[Dan Sugalski]

Okay, I've added in two new ops to take advantage of the new vtable
entries. There's now a can and does op, which checks to see if a PMC
can or does a particular method or interface. They both look like:

can Ix, Py, Sz

with X set to true or false depending on whether Y can or can't do
the requested thing. (Same for does)

At the moment this'll unconditionally fail since nothing but
default.pmc does these, and it pitches a fit, but...

You left out the 'goto NEXT()'s to prevent the interpreter from
exploding in flames.

I've added them, as well as suppressing some "no return" warnings,
regenerating the native_pbc tests, and adding tsq & event stuff to
MANIFEST & MANIFEST.detailed.

Those native_pbc things are annoying.

D'oh! Thanks.
