That's bad, and especially bad in #13265 where it caused the number of sections to exceed what is apparently an internal limit in ld.bfd. Test Plan: I can only test this on Linux, and I am guessing at what the correct behavior is on Mac OS and Windows (and AIX I suppose). Testers on other platforms would be much appreciated, though I understand that the LLVM backend is broken on Mac OS currently for other reasons (#13378).
