  Changed paths:
    M clang/lib/Sema/UsedDeclVisitor.h

  Log Message:
  -----------
  DeferredDiagnosticsEmitter crashes

Patch VisitCXXDeleteExpr() in clang::UsedDeclVisitor to avoid it crashing
when the expression's destroyed type is null. According to the comments
in CXXDeleteExpr::getDestroyedType(), this can happen when the type to
delete is a dependent type.

Patch by Geoff Levner.
