Re: Comment 7:

Since end users will gain little benefit from being able to run the sched1 pass
on x86 code, I don't think this is a serious problem.

PR33928 (comments 108 and 111) give an example where -fschedule-insns on x64-64
gives a 14% speedup on some direct and inverse FFT codes, certainly not a
trivial difference.
