Anna Thomas a8474917f4 [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.
