    M clang/test/SemaCXX/cxx2b-overloaded-operator.cpp

  Log Message:
  [Clang] Correctly expand pack in binary subscript expression.

When constructing an array expression where the index expression
was a pack expansion, we would construct an ArraySubscriptExpr
instead of an CreateOverloadedArraySubscriptExpr, and pack
expansion would not occur - leading a crash during code gen
or a failure during constant evaluation
