History

Matthew Maurer dbff90c2a7 LLVM 18 x86 data layout update

With https://reviews.llvm.org/D86310 LLVM now has i128 aligned to
16-bytes on x86 based platforms. This will be in LLVM-18. This patch
updates all our spec targets to be 16-byte aligned, and removes the
alignment when speaking to older LLVM.

This results in Rust overaligning things relative to LLVM on older LLVMs.

This alignment change was discussed in rust-lang/compiler-team#683

See #54341 for additional information about why this is happening and
where this will be useful in the future.

This *does not* stabilize `i128`/`u128` for FFI.
