Adding the language WG as a reviewer in case others have opinions.

According to https://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#362 
this was resolved in CD1 and we track it as being not applicable to us 
(https://clang.llvm.org/cxx_dr_status.html#362). (Is our status actually 
correct for this?)

To me, it depends on what it does to compile times and memory overhead for the 
compiler when run on large projects. If the extra tracking is cheap and doesn't 
really impact anything, I think it's reasonable to want to match GCC's 
behavior. If it turns out this is expensive, I'm less keen on matching GCC.
