new WAITCNT, looking for testers

fki

i wrote an alternative WAITCNT, which tests on entry whether the target already passed.
Therefor the COG does not halt for a full cnt overflow period.
Maximum wait time is halved.

it is discussed under:

i dont have a fpga-board. i would provide the new cog_alu.v and cog.v and a testcode. who can run that for me?

This is a good idea - another variant that could be tested at the same time,is a change from '<>' to '<=' on the wait-while test. In the original process equality-test is slightly smaller/faster, but FPGAs have HW carry chains, and faster fabric, so could give different results.
