Rollup merge of #135785 - folkertdev:s390x-vector-passmode-direct, r=bjorn3 
use `PassMode::Direct` for vector types on `s390x`

closes https://github.com/rust-lang/rust/issues/135744
tracking issue: https://github.com/rust-lang/rust/issues/130869

Previously, all vector types were type erased to `Ni8`, now we pass non-wrapped vector types directly. That skips emitting a bunch of casting logic in rustc, that LLVM then has to clean up. The initial LLVM IR is also a bit more readable.

This calling convention is tested extensively in `tests/assembly/s390x-vector-abi.rs`, showing that this change has no impact on the ABI in practice.
