David Anderson 8d2261e245 lib: initial implementation of an ECP5 EBR primitive
Only the core unconditioned primitive right now, and still needs refining.

David Anderson e6fa717507 Experiment comparing bsc-contrib's video timing generator with brute force
Brute force is a naively written state machine that combines both horizontal
and vertical timings into one, in a way that unrolls comically badly. It's
obviously uncompetitive as-is, but I wanted to use that as a starting point
to see how much bsc and yosys would still be able to cope with it.

The result: the worse code takes much longer for bluespec to evaluate, and it
consumes ~4x the amount of logic elements after synthesis. Less terrible than
I expected, to be honest!
