Summary: I'm not really happy about perpetuating the hackish fix for #8696, but at least in the context of building with -fhpc, the performance cost should be negligible. I'm suspicious about PlainModuleInitLabel and the Windows stuff too, but I don't know what it does / can't test it (respectively) so I'll leave those alone for now. Hopefully out-of-process TH will save us from these hacks some day. The test is an adaptation of T8696. It's a bit more awkward since I couldn't think of a way to get cross-module tickbox references without optimizations (inlining), but ghci doesn't permit -O for some reason.
