Merge commit 924f773f5e26 from llvm git (by Younan Zhang):

[Clang] Don't diagnose missing members when looking at the instantiating class template (#180725)

  The perfect matching patch revealed another bug where recursive
  instantiations could lead to the escape of SFINAE errors, as shown in
  the issue.

  Fixes https://github.com/llvm/llvm-project/issues/179118

This fixes compile errors in the www/qt5-webengine port.
