I think this might be the real bug, or something related.

current_function_decl is only null when we're not inside a function.
One possible fix is to test for current_function_section inside
unlikely_text_section_p. However, I think that begs the question
of what in the world is actually going on in rs6000_assemble_integer.
Why are we testing for emitting data in text sections?
