[PATCH] D96332: [RISCV] Add support for selecting vid.v from build_vector

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added a comment.

This was partly motivated to test the waters on how best to bring the fixed-length support up to speed with the scalable support.  The main concern is obviously the number of patterns we'd introduce, and having more-or-less copy/pasted code. Adding the `_VL` seems to me like a reasonable approach for our existing custom nodes like `VID`, but what about for SETCC, INSERT_ELEMENT, etc? Should scalable- and fixed- nodes both be custom-lowered to a VL version?
