The test case here is just going to be something like `_SomeSplitBitIntType x =
(unsigned long) &someVariable;`. What code do we actually produce for this?
Sometimes we'll be able to fall back on dynamic initialization, but that's not
always an option.
Ideally, it's just invalid to do something like that. It certainly needs to be
diagnosed if the integer type is narrower than the pointer, and wider is also
problematic, although less so and in a different way.
