PR c++/88049 - ICE with undefined destructor and anon namespace.
A type in an anonymous namespace can never be merged with one from
another translation unit, so a member of such a type is always its own
prevailing decl.
* lto-symtab.c (lto_symtab_prevailing_virtual_decl): Return early
for a type in an anonymous namespace.
