* sched.c (canon_rtx): Recursively look for equivalences;
look for expressions equivalent to MEMs.
(true_dependence): Canonicalize inputs before operating
on their values.
(anti_dependence, output_dependence): Likewise.
* jump.c (follow_jumps): Don't follow an unconditional jump
that is not a simple_jump.
