v0.0.0-7381-gc61103afe

Remove codegen specialization for priority selects.

We previously specialized the codegen of priority selects when the selector was never zero. The specialization would call `$error()` if the selector was zero and propagate `X`, the idea being that this form might synthesize to something smaller.

Unfortunately, this specialization causes more headaches than it is worth. The `$error()` call isn't a real assertion, so it could spuriously fire. We also generally prefer to avoid propagating X explicitly.

Benchmarks showed that this specialization didn't give a net benefit on our corpus, so it seems better to avoid the headaches by removing it.

Fixes google/xls#1481.

Add test with channel declared in a proc.

The channel results in a FIFO instantiation connected two instantiated procs. No functional change to codegen required.

Also, create a test-only RTL FIFO library out of existing test FIFOs in block_generator_test.

Add a 'Forced' state to lazy_dag_cache and children

This allows one to set a particular key to a known fixed value irrespective of the computations of other nodes. This Forced key acts as a break on updates propagating.
