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. r? ````@taiki-e````
