Anna Thomas fb0da33fc1 [LV] Avoid computing the register usage for default VF. NFC ...

These are changes to reduce redundant computations when calculating a
feasible vectorization factor:
1. early return when target has no vector registers
2. don't compute register usage for the default VF.

Suggested during review for D37702.
