  Changed paths:
    M clang/include/clang/Basic/Specifiers.h
    M clang/lib/Basic/Diagnostic.cpp
    M clang/lib/Basic/IdentifierTable.cpp
    M clang/test/SemaObjC/nullable-result.m

  Log Message:
  -----------
  Give NullabilityKind a printing operator<<

This is more useful for debug/test than getNullabilitySpelling:
 - default form has uglifying underscores
 - non-default form crashes on NullableResult
 - both return unhelpfully verbose strings for Unspecified
 - operator<< works with gtest, formatv, etc
