You should update `dump_ir_resource_load()`.

If you don't need to access the value while parsing, defer this error message to the code generation phase. This way you give the constant folding pass the opportunity to let the compiler accept constant expressions which are not constant values (like `1+2` instead of `3`).

How hard would it be to actually run the shader?
What happens when you try to perform a multisampled load on a non-multisampled resource, or the other way around?
