Move `llvm.x86.*` shims into `shims::x86` and implement `_addcarry_u32` and `_subborrow_u{32,64}`
This PR moves all `llvm.x86.*` shims into `shims::x86` and adds `llvm.x86.addcarry.32`, `llvm.x86.subborrow.32` and `llvm.x86.subborrow.64`.
Additionally, it fixes the input carry semantics of `llvm.x86.addcarry.32`. The input carry is an 8-bit value that is interpreted as 1 when it is non-zero.
