Jordan Rose 06dd406e27 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

Douglas Gregor aea7afdc13 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.
