  -----------
  [LV] Use getVectorLoopRegion to retrieve header. (NFC)

Update all places that currently assume the entry block to the plan is
also the vector loop header to use getVectorLoopRegion instead.

getVectorLoopRegion will keep doing the right thing when the pre-header
is modeled explicitly (and becomes the new entry block in the plan).
