https://github.com/momchil-velikov created https://github.com/llvm/llvm-project/pull/116829
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
`FCVTLT`, and `FCVTX` instructions.

Subject: [PATCH 1/4] [AArch64] Generate zeroing forms of certain SVE2.2
instructions (1/11)
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.
