[AArch64] Add SVE2 version of qfind_first_byte_of #2305
Conversation
This patch adds optimised routines for "find first" methods for AArch64 targets that support SVE2. The implementation is based on the already existing SSE routines.

Sorry about that, I somehow missed this PR when you first put it up. I've imported it now and the tests are running. |

No worries! Please let me know if you need anything or have any suggestions. |

Still working on the internal version of this to get it compiling properly in all of our build environments (most of it is just getting our internal build system configured properly). Hopefully I've just submitted the final fix for testing, but I've thought that before, so we'll see what happens. |

Thanks for the update, @Orvid! Please let me know if there's anything I can help with! |

I've placed the new routines in our (NVIDIA) external folder and renamed the NoSSE methods to NoSIMD (please let me know if you have a better suggestion). On Grace, the new routines show very significant speedups on the Range Find benchmark.
