simplify: support a bunch of new operations, some fixups

Add support for move, cmp, new-array and filled-new-array.

Fixups:
 * Accept return-object as well as plain return
 * check-cast should accept arrays
 * Use the new 'doublify' function for wide args in invoke
 * add '.class' after the classname in const-class op
