Review request for Default. Description ------- Mark ARM IT (if-then) instructions as nops. ARM's IT instructions predicate up to the next 4 instructions on various condition codes. IT instructions really just send control signals to the decoder, after decode they do not read or write any registers. Marking them as nops (along with the other patch that drops nops at decode) saves execution resources and bandwidth.
