  Log Message:
  -----------
  [SDAG] allow more cast folding for vector sext-of-setcc

This is a follow-up to D103280 that eases the use restrictions,
so we can handle the motivating case from:
https://llvm.org/PR50055

The loop code is adapted from similar use checks in
ExtendUsesToFormExtLoad() and SliceUpLoad(). I did not see an
easier way to filter out non-chain uses of load values.
