whitequark 5157691f0e write_cxxrtl: statically schedule comb logic and localize wires. 
This results in further massive gains in performance, modest decrease
in compile time, and, for designs without feedback arcs, makes it
possible to run eval() once per clock edge in certain conditions.

whitequark d6d7273421 write_cxxrtl: elide wires for results of comb cells used once. 
This results in massive gains in performance, equally massive
reduction in compile time, and improved readability.

This commit adds a basic implementation that isn't very performant
but implements most of the planned features.
