SVE2.2 introduces instructions with predicated forms with zeroing of the inactive lanes. This allows in some cases to save a `movprfx` or a `mov` instruction when emitting code for `_x` or `_z` variants of intrinsics. This patch adds support for emitting the zeroing forms of `ABS`, `NEG`, `FABS`, and `FNEG` instructions.
