Description
Continuation of https://github.com/Rust-GCC/gccrs/issues/4791, we do not support compilation of platform intrinsic built-ins yet, e.g:
extern "platform-intrinsic" {
//pub fn simd_select_bitmask
pub fn simd_eq<T, U>(x: T, y: T) -> U;
pub fn simd_ne<T, U>(x: T, y: T) -> U;
pub fn simd_lt<T, U>(x: T, y: T) -> U;
pub fn simd_le<T, U>(x: T, y: T) -> U;
pub fn simd_gt<T, U>(x: T, y: T) -> U;
pub fn simd_ge<T, U>(x: T, y: T) -> U;
}

Research direction
Start by reading issue 4791, then trace how gccrs handles extern ABI declarations and the listed platform-intrinsic functions. The work is done when the shown simd_eq, simd_ne, simd_lt, simd_le, simd_gt, and simd_ge declarations compile successfully.
