Yup, dsymutil looks good now, thanks

> There's a couple of switches in llvm/lib/DWARFLinker that look like they want a DW_TAG_template_alias:
DependencyTracker::isTypeTableCandidate in DependencyTracker.cpp
AcceleratorRecordsSaver::save in AcceleratorRecordsSaver.cpp. I'm not sure what a test for those would look like but I can look into it if you'd like?

Good question, I'm not familiar with these either, but would make sense to address these eventually. Though I don't think it's urgent atm since `-gtemplate-alias` isn't the default
