Remove enum_from_u32.

Browse source 
It's a macro that just creates an enum with a `from_u32` method. It has
two arms. One is unused and the other has a single use.

This commit inlines that single use and removes the whole macro. This
increases readability because we don't have two different macros
interacting (`enum_from_u32` and `language_item_table`).
