- Ensure we don't try and combine a UUNPKHI.
- Remove incorrect IsExapanding argument to getMaskedLoad.
- Explicitly check for and create new PTRUE for mask.
- Properly check that the PTRUE we are creating can be represented at the current VL.
- Remove extract_subvector ptrue combine as it is no longer needed.
