  [AArch64] Fix partial_reduce v16i8 -> v2i32 (#177119)

The lowering doesn't need to check for `ConvertToScalable`, because it
lowers to another `PARTIAL_REDUCE_*MLA` node, which is subsequently
lowered using either fixed-length or scalable types.

This fixes https://github.com/llvm/llvm-project/issues/176954

Re-generate check lines

The check lines for SME were different because of sub-register liveness,
which is enabled for streaming functions on trunk, but isn't enabled on
the release branch.

(cherry picked from commit de997639876db38d20c7ed9fb0c683a239d56bf5)
