  [NFC][LoopVectorize] Simplify preferPredicateOverEpilogue interface

Given just how many arguments we pass to
preferPredicateOverEpilogue and considering this list may
grow over time I've decided to pass in a pointer to a new
TailFoldingInfo structure instead, similar to what we do
with IntrinsicCostAttributes, etc. In addition, many of the
arguments we pass in are actually available in the
LoopVectorizationLegality class so I've managed to
reduce the set of pointers that we need to pass in the
TailFoldingInfo struct.
