       1 -> 3 [ -> 0 ]  or

           A VFP instruction has been seen which overwrites any of regs[*].
           We must make a veneer!  Reset state to 0 before examining next
           instruction.

       2 -> 0
           If we fail to match anything in state 2, reset to state 0 and reset
           the instruction pointer to the instruction after 'first_fmac'.

     If the VFP11 vector mode is in use, there must be at least two unrelated
     instructions between anti-dependent VFP11 instructions to properly avoid
     triggering the erratum, hence the use of the extra state 1.  */
