add x86-sse2 (32bit) ABI that requires SSE2 target feature This is the first commit of rust-lang#135408: The primary goal of this is to make SSE2 required for our i686 targets (at least for the ones that use Pentium 4 as their baseline), to ensure they cannot be affected by rust-lang#114479. This has been MCPd in rust-lang/compiler-team#808, and is tracked in rust-lang#133611. We do this by defining a new ABI that these targets select, and making SSE2 required by the ABI (that's the first commit). That's kind of a hack, but it is the easiest way to make a target feature required via the target spec. In a follow-up change (rust-lang#135408), we can actually make use of SSE2 for the ABI, but that is running into some infrastructure issues. r? `@workingjubilee` try-job: aarch64-apple try-job: aarch64-gnu try-job: aarch64-gnu-debug try-job: test-various try-job: x86_64-gnu-nopt try-job: dist-i586-gnu-i586-i686-musl

x86: use SSE2 to pass float and SIMD types This builds on the new X86Sse2 ABI landed in rust-lang#137037 to actually make it a separate ABI from the default x86 ABI, and use SSE2 registers. Specifically, we use it in two ways: to return `f64` values in a register rather than by-ptr, and to pass vectors of size up to 128bit in a register (or, well, whatever LLVM does when passing `<4 x float>` by-val, I don't actually know if this ends up in a register).
