I don't know too much about this. I guess have a DiagReceiver to force the
emitting order is a good thing but it is kind of weird to have this just for
unused warning.
I am guessing my suspect of removing decl from the scope is the cause of the
slow down. Maybe we just force order on iteration?
================
Comment at: clang/include/clang/Sema/Scope.h:310
decl_range decls() const {
return decl_range(DeclsInScope.begin(), DeclsInScope.end());
----------------
I wonder if it would be easy if you just sort here and provide a consistent
ordering when iterating?
