dtrace: allow invop handler to specify number of insns to skip

Rather than unconditionally skipping one instruction, repurpose the
unused return value of the invop handler to allow it to specify the
amount to skip.  (In the common case where it knows how many
instructions to skip at all times, this is more efficient.)
