This adds support for the simd variants of the pointer provenance intrinsics, which are `simd_cast_ptr`, `simd_expose_addr`, and `simd_from_exposed_addr`. The preconditions for each intrinsic are adapted from rustc_codegen_llvm to preserve compatibility. Each of these intrinsics are implemented as calling the non-simd variant of each intrinsic on each lane. This is enough to enable the UI test `ui/simd/intrinsic/ptr-cast.rs` to pass.
