Description

u32::max / u32::min cannot be used as they require OpCapability U8. They should just work out of the box.

Workaround: use u32::clamp() instead.

It's the Ordering enum. it has #[repr(i8)] (with -1, 0, +1 values)

Maybe we should special case the Ordering enum to be a u32?

Research direction

Start by reproducing the u32::max and u32::min capability error and compare it with the u32::clamp() workaround. Trace how the Ordering enum and its #[repr(i8)] values affect capability requirements; done means the max and min operations work without requiring OpCapability U8.
