It is not a matter of efficiency, but primarily that RA can't do anything in
many cases after propagating hard registers into instructions. This PR is just
one of the many cases.

Well, often sel-sched just does not discriminate hardregs and pseudos when
checking if renaming/substitution may be applied. Sure, as a matter of
efficiency we should probably disallow substitution

Why does sel-sched try to propagate hard registers into insns before RA? The
whole point of the combiner changes was not to do that, so that the RA can do
better job.

We have a pseudo:SI<-hardreg:SI assignment followed by
pseudo:DF<-float(pseudo:SI) conversion, and we substitute the latter through
the former, creating a pseudo:DF<-float(hardreg:SI) insn that fails in
