Expand description

State transition for FieldMachine.

One call handles every pipeline stage at once, each working on a different bundle: S1 for the context whose turn it is, S2 and S3 for the bundles issued one and two cycles earlier, S4 for the bank-L commit, and the write-back of whatever the units return this cycle. Values read from q are memory outputs addressed in the previous cycle; values written to d take effect at the next edge.
