Once we've merged the clauses' constants, we need to....
1. Swap where necessary so non-pcrel constants are correctly encoded.
2. Swap where necessary so pcrel constants are in canonical positions.

These work as you would expect: first handling paired constants
(swapping to a canonical form to deduplicate), then handling unpaired
constants (packing together in a canonical form). Most of the added
complexity is from pcrel handling, but we impose strict invariants on
pcrel (no more than one PC-relative constant per clause, only M1=4 mode)
without which the algorithm would be even uglier.

The number of register writes in a tuple must be bounded by a number
based on the number of register reads in the succeeding tuple, since
writes and reads are interleaved. This helper calculates that number of
reads, noting that not every read actually counts - if the preceding
tuple writes to a read source, that will become a temporary instead of
consuming a register slot.
