-; Check that when argument promotion changes a function in some parent node of
-; the call graph, any analyses that happened to be cached for that function are
-; actually invalidated. We are using `demanded-bits` here because when printed
-; it will end up caching a value for every instruction, making it easy to
-; detect the instruction-level changes that will fail here. With improper
-; invalidation this will crash in the second printer as it tries to reuse
-; now-invalid demanded bits.
