  Added a flag to indicate whether an exception took place on the first
  or second half of a VLIW instruction--will be zero in non-VLIW mode,
  equivalent to the second half of the instruction having caused the
  exception. (Expect these flags to be reordered some time in the future into
  a less haphazard ordering ...)
  
  Vastly simplified the pipeline logic, primarily for op_stall, but also touched
  opA and opB. (Trying to fit within timing on Spartan 6 ...)
  
  Changed division instruction to include a reset on clear_pipeline, to make
  certain [BC $addr; DIV Rx,Ry ] works regardless of whether the condition is
  true.
