Added throw-verification-error instruction.

This is for the deferred verifier error reporting.  It replaces OP_UNUSED_ED.
The instructions aren't actually used yet, which is good since the x86
version hasn't been written yet.

The mterp regen also pushed out some recent-ish changes that hadn't
propagated to the armv4t sources.
