[Haowei Wu via Phabricator via llvm-commits]

Hi, we found out that this patch breaks following tests in the Fuchsia's stage-2 mac clang builders:

  Clang :: Refactor/Extract/ExtractExprIntoFunction.cpp
  Clang :: Refactor/Extract/ExtractionSemicolonPolicy.cpp
  Clang :: Refactor/Extract/ExtractionSemicolonPolicy.m
  Clang :: Refactor/Extract/FromMethodToFunction.cpp
  Clang :: Refactor/Extract/ObjCProperty.m

An example of the failure: https://ci.chromium.org/ui/p/fuchsia/builders/prod/clang-mac-x64/b8823769353085181809/overview . And test error messages can be found at https://ci.chromium.org/ui/p/fuchsia/builders/prod/clang-mac-x64/b8823769353085181809/test-results . These failures only happens in stage 2 build so it took us some time to bisect and confirm it. Could you take a look please? And if it takes a long time to fix, could you revert this change first please? Thanks.
