  Log Message:
  [AArch64][SME] Promote mask for masked load to a similar type size with load value.

The legalizer could keep an original mask type of masked load combined with
sign/zero extend, but we have to extend the mask to a type similar to our
combined load otherwise instruction selection could not lower the load.
