<pre>
    The IR should define a `!nofpclass` metadata type, equivalent to the `nofpclass` attribute. This will just encode an integer equivalent to the attribute's bitmask.

This will be useful to complete the migration to only use `byref` arguments with amdgpu_kernel. If we stop using direct value arguments, we currently have no equivalent way of representing the nofpclass annotation.
