I'd initially restricted the workaround to `gcc` because the reduced testcase attached to the GCC PR works when compiled with `clang++` instead of `g++`.  However, a bootstrap build is still nightmarishly bad on Solaris/sparcv9: the 11.0.0-rc1 one had 4817 failures, a fresh one on master with the workaround applied to both `gcc` and `clang` is down to 1365.

So there's at least some improvement, but still a long way to go.
