  Log Message:
  -----------
  [msan] Handle Intrinsic::vector_reduce_f{add,mul} (#125615)

This adds handleVectorReduceWithStarterIntrinsic() (similar to
handleVectorReduceIntrinsic but for intrinsics with an additional
starting parameter) and uses it to handle
Intrinsic::vector_reduce_f{add,mul}.

Updates the tests from https://github.com/llvm/llvm-project/pull/125597
