Jonathan Westhues 60925e4040 A ~10x speedup in the solver. Simplify equations before evaluating 
or taking partials (constant folding). Also keep a little hash
table to mark with params are used in each equation, in order to
quickly discard trivial partial derivatives. This is solving a
64x64 system in <20 ms. I suspect this is now much faster than
Sketchflat.

Slightly fake situation, though, since substitution solver has not
yet been written, and no partitioning. I'll do those next.
