russell.gallop added a comment.

We also see an assertion failure prior to the revert. At r329738:

  $ cat test.cpp
  template <class> struct A {
    template <class _Other> using rebind_alloc = _Other;
  };
  template <class _Alloc> struct _Wrap_alloc {
    template <class _Other>
    using rebind_alloc = typename A<_Alloc>::template rebind_alloc<_Other>;
    template <class> using rebind = _Wrap_alloc;
  };
  _Wrap_alloc<int>::rebind<int> w;
  
  $ clang++ -c test.cpp
  
  $ clang++ -c test.cpp -ftime-report
  clang-7: llvm/lib/Support/Timer.cpp:133: void llvm::Timer::startTimer(): Assertion `!Running && "Cannot start a running timer"' failed.
