3513886c - [msan] Generalize handleVectorReduceIntrinsic to support Arm NEON add reduction to scalar (#125288)

[msan] Generalize handleVectorReduceIntrinsic to support Arm NEON add reduction to scalar (#125288) This generalizes handleVectorReduceIntrinsic to allow intrinsics where the return type is not the same as the fields. This patch then applies the generalized handleVectorReduceIntrinsic to support the following Arm NEON add reduction to scalar intrinsics: llvm.aarch64.neon.{faddv, saddv, uaddv}. Updates the tests from https://github.com/llvm/llvm-project/pull/125271
