Tidy up sema processing of attribute "nonull":
...
- warn about nonnull being applied to functions with no pointer arguments
- continue processing argument list in the attribute when we encounter a non-pointer parameter being marked as nonnull
- when no argument list is specified, only mark pointers as nonnull. This fixes PR 2732 and radar 6188814.

Add EXTWARN Diagnostic class.
...
- Like EXTENSION but always generates a warning (even without
-pedantic).
- Updated ptr -> int, int -> ptr, and incompatible cast warnings to
be EXTWARN.
- Other EXTENSION level diagnostics should be audited for upgrade.
- Updated several test cases to fix code which produced unanticipated
warnings.
