Add fix-it notes to the nullability consistency warning. This is especially important for arrays, since no one knows the proper syntax for putting qualifiers in arrays. nullability.h:3:26: warning: array parameter is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified) void arrayParameter(int x[]); ^ nullability.h:3:26: note: insert '_Nullable' if the array parameter may be null void arrayParameter(int x[]); ^ _Nullable nullability.h:3:26: note: insert '_Nonnull' if the array parameter should never be null void arrayParameter(int x[]); ^ _Nonnull rdar://problem/29524992 llvm-svn: 290132 2016-12-20 04:58:20 +08:00			`// expected-note@-3 {{insert '_Nullable' if the pointer may be null}}`

Replace __double_underscored type nullability qualifiers with _Uppercase_underscored Addresses a conflict with glibc's __nonnull macro by renaming the type nullability qualifiers as follows: __nonnull -> _Nonnull __nullable -> _Nullable __null_unspecified -> _Null_unspecified This is the major part of rdar://problem/21530726, but does not yet provide the Darwin-specific behavior for the old names. llvm-svn: 240596 2015-06-25 06:02:08 +08:00			`void system2(int * _Nonnull);`
