Auto merge of #141309 - RalfJung:x86-simd-abi, r=tgross35,nikic,workingjubilee
x86 (32/64): go back to passing SIMD vectors by-ptr

Fixes https://github.com/rust-lang/rust/issues/139029 by partially reverting https://github.com/rust-lang/rust/pull/135408 and going back to passing SIMD vectors by-ptr on x86. Sadly, by-val confuses the LLVM inliner so much that it's not worth it...

Also fixes https://github.com/rust-lang/rust/issues/141848 by no longer actually using vector registers with the "Rust" ABI.
