So like this? I've also changed get_compute_type so that it will DTRT
even for -mavx and V4DImode vectors, so e.g. f5/f6/f8 routines in
avx-pr57233.c improve. Also, even for shifts by scalar, if e.g. target
doesn't have shifts by scalar at all, and

Hi!
Since we've started folding (a n) | (a (bitsize - n)) etc.
into rotates even vectors, we've regressed code quality on targets
where we do have vector shifts, but don't have vector rotates.
The following patch attempts to fix it, by telling veclower pass
not to actually lower it if we have
