gcc9-pr89933.patch
Untested fix. The code added in r234626 aka PR70297 fix assumes that the type
is not its main variant, which is the case here. If we wanted to remove the
main variant from its variant list, we'd need to adjust all the variants in the
list (if any) to some other main variant. I'd think just changing the
TYPE_NAME is better in this case, usually there won't be any variants in that
case and the remove type won't be referenced from anywhere, but if it is, we
won't ICE because it refers to ggc_freed TYPE_DECL.
