Don't emit clashing decl lint for FFI-safe enums.
An example of an FFI-safe enum conversion is when converting Option<NonZeroUsize> to usize. Because the Some value must be non-zero, rustc can use 0 to represent the None variant, making this conversion is safe. Furthermore, it can be relied on (and removing this optimisation already would be a breaking change).
