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).

## Cargo

-   [Add terminal integration via ANSI OSC 9;4 sequences](rust-lang/cargo#14615)
-   [chore: bump openssl to v3](rust-lang/cargo#15232)
-   [feat(package): add --exclude-lockfile flag](rust-lang/cargo#15234)

<a id="1.87.0-Compatibility-Notes"></a>

## Compatibility Notes

-   [Rust now raises an error for macro invocations inside the `#![crate_name]` attribute](rust-lang/rust#127581)
-   [Unstable fields are now always considered to be inhabited](rust-lang/rust#133889)
-   [Macro arguments of unary operators followed by open beginning ranges may now be matched differently](rust-lang/rust#134900)
-   [Make `Debug` impl of raw pointers print metadata if present](rust-lang/rust#135080)
-   [Warn against function pointers using unsupported ABI strings in dependencies](rust-lang/rust#135767)
-   [Associated types on `dyn` types are no longer deduplicated](rust-lang/rust#136458)
-   [Forbid attributes on `..` inside of struct patterns (`let Struct { #[attribute] .. }) =`](rust-lang/rust#136490)
-   [Make `ptr_cast_add_auto_to_object` lint into hard error](rust-lang/rust#136764)
-   Many `std::arch` intrinsics are now safe to call in some contexts, there may now be new `unused_unsafe` warnings in existing codebases.
-   [Limit `width` and `precision` formatting options to 16 bits on all targets](rust-lang/rust#136932)
-   [Turn order dependent trait objects future incompat warning into a hard error](rust-lang/rust#136968)
-   [Denote `ControlFlow` as `#[must_use]`](rust-lang/rust#137449)
-   [Windows: The standard library no longer links `advapi32`, except on win7.](rust-lang/rust#138233) Code such as C libraries that were relying on this assumption may need to explicitly link advapi32.
-   [Proc macros can no longer observe expanded `cfg(true)` attributes.](rust-lang/rust#138844)
-   [Start changing the internal representation of pasted tokens](rust-lang/rust#124141). Certain invalid declarative macros that were previously accepted in obscure circumstances are now correctly rejected by the compiler. Use of a `tt` fragment specifier can often fix these macros.
-   [Don't allow flattened format_args in const.](rust-lang/rust#139624)

Cargo
-----
- [Add terminal integration via ANSI OSC 9;4 sequences]
  (rust-lang/cargo#14615)
- [chore: bump openssl to v3]
  (rust-lang/cargo#15232)
- [feat(package): add --exclude-lockfile flag]
  (rust-lang/cargo#15234)

Compatibility Notes
-------------------
- [Rust now raises an error for macro invocations inside the
  `#![crate_name]` attribute]
  (rust-lang/rust#127581)
- [Unstable fields are now always considered to be inhabited]
  (rust-lang/rust#133889)
- [Macro arguments of unary operators followed by open beginning
  ranges may now be matched differently]
  (rust-lang/rust#134900)
- [Make `Debug` impl of raw pointers print metadata if present]
  (rust-lang/rust#135080)
- [Warn against function pointers using unsupported ABI strings in dependencies]
  (rust-lang/rust#135767)
- [Associated types on `dyn` types are no longer deduplicated]
  (rust-lang/rust#136458)
- [Forbid attributes on `..` inside of struct patterns (`let Struct
  { #[attribute] .. }) =`]
  (rust-lang/rust#136490)
- [Make `ptr_cast_add_auto_to_object` lint into hard error]
  (rust-lang/rust#136764)
- Many `std::arch` intrinsics are now safe to call in some contexts,
  there may now be new `unused_unsafe` warnings in existing codebases.
- [Limit `width` and `precision` formatting options to 16 bits on all targets]
  (rust-lang/rust#136932)
- [Turn order dependent trait objects future incompat warning into a hard error]
  (rust-lang/rust#136968)
- [Denote `ControlFlow` as `#[must_use]`]
  (rust-lang/rust#137449)
- [Windows: The standard library no longer links `advapi32`, except
  on win7.] (rust-lang/rust#138233)
  Code such as C libraries that were relying on this assumption
  may need to explicitly link advapi32.
- [Proc macros can no longer observe expanded `cfg
  (true)` attributes.](rust-lang/rust#138844)
- [Start changing the internal representation of pasted tokens]
  (rust-lang/rust#124141). Certain invalid
  declarative macros that were previously accepted in obscure
  circumstances are now correctly rejected by the compiler. Use of
  a `tt` fragment specifier can often fix these macros.
- [Don't allow flattened format_args in const.]
  (rust-lang/rust#139624)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- [Update to LLVM 20]
  (rust-lang/rust#135763)

x86 (32/64): go back to passing SIMD vectors by-ptr

Fixes rust-lang#139029 by partially reverting rust-lang#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 rust-lang#141848 by no longer actually using vector registers with the "Rust" ABI.
