    add new stages etc. to get multiply working without xer_ca

removing xer_ca from the DIV and MUl pipelines (both on input and
output) needs a bit of tweaking.

it's important because unnecessary registers being read/written to
creates dependencies that create chaining and prevent opportunities
for parallelism.
