  [LV] Remove scalable constraints on creating bitcasts

InnerLoopVectorizer::createBitOrPointerCast only supported fixed
length vectors since it hadn't been updated. Supporting scalable
vectors is just a matter of changing types and using elementcount
instead of numelements, since there's nothing which actually relies
on knowing the exact length of the vector.
