After r353547, Firefox PGO builds fail with...

lld-link: error: relocation against symbol in discarded section:
__profc_?_Tidy_deallocate@?$basic_string at DU?$char_traits at D@std@@V?$allocator at D@2@@std@@QEAAXXZ.51057184705

...which is surprising because https://reviews.llvm.org/D57929 says that this
was the very error message that the patch was attempting to fix.

The linkrepro is too large for Bugzilla but I'm happy to share it upon request.
