Addressed comments from Nemanja:

- various variable changes
- update comment/documentation
- corrected the index for the `xxsplti32dx` instruction for LE/BE
- Updated the instruction to use `u1imm` instead of `i1imm` so the index in assembly can be `0/1`, and this allows us the index to be `i32` in the pattern.
