Now `unknown_mem` is removed.
FP access has more complicated restrictions. For example read access to FP
status bits require setting `strictfp` attribute. The initial intent was to
uses `NoModRef` for FP locations as this is the common case. Now it requires
more careful treatment in attribute deduction.
