Fix for PR1075: bottom-up register-reduction scheduling actually increases register pressure.

- Fixed bugs in sethi-ullman number computation and priority queue comparison
functions.
- Separate code that handles priority computation special cases from SU number computation.

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

This reduces selectiondag time on kc++ from 5.43s to 4.98s (9%). More
significantly, this speeds up the default ppc scheduler from ~1571ms to 1063ms,
a 33% speedup.
