There was some level of misunderstanding here, but even looking
closer, my suggestion wouldn't help. Still, I'll be more
verbose:
I don't think you got me here. I mean, do as in 6cb68940dcf9
and for VAX create a define_insn_and_split, recognized at reload
time, where you recognize the MULT form and translate that into
the ASHIFT form, to help reload.
But looking closer, the situation requires a non-cc0-clobbering
insn, but AFAICT VAX only has MOVA and it clobbers
VAX_PSL_REGNUM. Nevermind...
