This has gone unfixed for months because the fix has been found to introduce some small performance regressions. However, Andy has recommended that, at this point, we fix this to avoid further dependence on the incorrect behavior (and then follow-up separately on any regressions), and I agree. Fixes PR18883. This fixes a possible "ran out of registers" error when compiling www/firefox 45.0 on i386. Direct commit to stable/10, because head already has this fix since the llvm/clang 3.6.0 import.
