  Log Message:
  -----------
  [X86] Make reduceMaskedLoadToScalarLoad/reduceMaskedStoreToScalarStore work for avx512 after type legalization.

The scalar elements of the vXi1 build_vector will have been type legalized to i8 by padding with 0s. So we can't check for all ones. Instead we should just look at bit 0 of the constant.
