This reverts commit 9a99944df068b29b905cd8ba9a2132cc6382b6fb. Due to test suite failures on all our SVE buildbots e.g.: https://lab.llvm.org/buildbot/#/builders/184/builds/7375 clang: ../llvm/llvm/lib/Target/AArch64/AArch64TargetTransformInfo.cpp:3565: InstructionCost llvm::AArch64TTIImpl::getShuffleCost(TTI::ShuffleKind, VectorType *, ArrayRef<int>, TTI::TargetCostKind, int, VectorType *, ArrayRef<const Value *>): Assertion `Mask.size() == TpNumElts && "Expected Mask and Tp size to match!"' failed.
