Revised type compatibility check w.r.t. handling of attributes.
We now distinguish 3 modes (instead of 2 previously) for attributes: 1- strict compatibility, 2- ignore top-level attrs, 3- ignore all attrs recursively.
In strict mode, const/volatile/restrict attributes must be identical, but nonstandard attributes may vary.
Also: ignore top-level attrs when comparing function argument types, like GCC/Clang do.
Net result is fewer warnings and type-checking that is closer to GCC/Clang.
