[PATCH] D42133: [AArch64] Improve code generation of vector mask build

[Eli Friedman via Phabricator via llvm-commits]

You should probably just fix AArch64TargetLowering::LowerBUILD_VECTOR to generate the right node in the first place.  Not sure why it isn't picking up these particular cases, but it has code to handle constant BUILD_VECTORS.
