Rollup merge of #131586 - taiki-e:s390x-vector-abi, r=compiler-errors,uweigand
Support s390x z13 vector ABI cc #130869 This resolves the following fixmes: - https://github.com/rust-lang/rust/blob/58420a065b68ecb3eec03b942740c761cdadd5c4/compiler/rustc_target/src/abi/call/s390x.rs#L1-L2 - https://github.com/rust-lang/rust/blob/58420a065b68ecb3eec03b942740c761cdadd5c4/compiler/rustc_target/src/spec/targets/s390x_unknown_linux_gnu.rs#L9-L11 Refs: Section 1.2.3 "Parameter Passing" and section 1.2.5 "Return Values" in ELF Application Binary Interface s390x Supplement, Version 1.6.1 (lzsabi_s390x.pdf in https://github.com/IBM/s390x-abi/releases/tag/v1.6.1) This PR extends ~~https://github.com/rust-lang/rust/pull/127731~~ https://github.com/rust-lang/rust/pull/132173 (merged) 's ABI check to handle cases where `vector` target feature is disabled. If we do not do ABI check, we run into the ABI problems as described in https://github.com/rust-lang/rust/issues/116558 and https://github.com/rust-lang/rust/issues/130869#issuecomment-2408268044, and the problem of the compiler generating strange code (https://github.com/rust-lang/rust/pull/131586#discussion_r1799003554). cc `@uweigand` `@rustbot` label +O-SystemZ +A-ABI
