[AArch64][GlobalISel] Use TST for comparisons when possible
Porting over the part of `emitComparison` in AArch64ISelLowering where we use
TST to represent a compare.
- Rename `tryOptCMN` to `tryFoldIntegerCompare`, since it now also emits TSTs
when possible.
- Add a utility function for emitting a TST with register operands.
- Rename opt-fold-cmn.mir to opt-fold-compare.mir, since it now also tests the
TST fold as well.
