LOG: [AArch64] Generate zeroing forms of certain SVE2.2 instructions (11/11) (#116837)
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 certain
`SXTB`, `UXTB`, `SXTH`, `UXTH`, `SXTW`, and `UXTW` instructions.
Added:
