…o clarify test

This patch implements Rust's equivalent of Clang's function pointer type discriminator computation used in pointer authentication. Compatibility with Clang is a primary goal. The discriminator produced for a given external "C" function type must match the value computed by Clang so that function pointers can be exchanged safely between Rust and C code while preserving pointer authentication semantics. The implementation mirrors Clang's behavior in `ASTContext::encodeTypeForFunctionPointerAuth`, ensuring that identical C-compatible function types produce identical discriminators. See: <https://clang.llvm.org/doxygen/ASTContext_8cpp.html#abb1375e068e807917527842d05cadea3>.

atomic volatile: add intrinsics Extend the atomic load/store intrinsics to also support volatile atomic load/store. Tracking issue: rust-lang#158947. Library APIs that use these intrinsics will be added inn a future PR. The GCC and cranelift implementations ignore the volatile flag, not sure how that should be implemented for them.

To `QuerySystem`, next to `query_vtables`. It's a better spot for it.

`MCOptions` is the name of the variable commonly used for instances of `MCTargetOptions`. Use the proper type name instead.
