[Bug rtl-optimization/41171] register allocator undoing optimal schedule

[bergner at gcc dot gnu dot org]

My patch solved the problem, but was very very neutral wrt SPEC2000 scores. 
Vlad's idea of moving update_equiv_regs() into its own pass before sched1 makes
sense to me and seems to produce better performing code too, so his patch wins.
:)  Thanks Vlad.
