[PATCH] D103082: [AArch64][SVE] Optimize svbool dupq ACLE intrinsic to fixed predicate patterns

[Eli Friedman via Phabricator via llvm-commits]

Do we really need a dedicated LLVM intrinsic to make the pattern-matching work here?  It would be better if we could leverage @llvm.experimental.vector.insert.nxv16i8.v16i8 or something like that.  Something along the lines of https://godbolt.org/z/Wz4azzKrP seems straightforward enough to match, and generates decent code even without any special patterns.
