[LV] Use shl for ((VF * Step) * vscale) in createStepForVF. (#153495)
Directly emit shl instead of a multiply if VF * Step is a power-of-2. The
main motivation here is to prepare the code and test for directly
generating and expanding a SCEV expression of the minimum iteration
count. SCEVExpander will directly emit shl for multiplies with
powers-of-2.
InstCombine will also performs this combine, so end-to-end this should
effectively by NFC.
