HA! tracked down and fixed a bug in MultiCompUnit's (new) write-mask
handling, where there was a test condition looking for write-request
signals coming in that would, because they were disabled, never going
once that was sorted, the new CompUnit-based unit test for ALU passed.
it uses the exact same unit tests as from the pipeline-only-based ALU
with the only difference between the tests being that one adds
MultiCompUnit on *top* of the other, this helps to confirm that
MultiCompUnit is functional.
i am very happy.
i'll do the same thing for the other pipelines.
