Description
Problem:
The compiler emits warnings about unused arguments in intrinsic functions without bodies (when #[rustc_intrinsic] is used). These arguments are inherently unused, but the warnings create unnecessary noise.
Proposed Solution:
Update the compiler to automatically suppress unused argument warnings for intrinsics without bodies. This eliminates the need for manual workarounds like prefixing variable names with _.
