re PR lto/66180 (many -Wodr false positives when building LLVM with -flto)
PR lto/66180
* ipa-devirt.c (type_with_linkage): Check that TYPE_STUB_DECL
is set; check for assembler name at LTO time.
(type_in_anonymous_namespace): Remove hacks, check that all
anonymous types are called "<anon>"
(odr_type_p): Simplify; add check for "<anon>"
(odr_subtypes_equivalent): Add odr_type_p check.
* tree.c (need_assembler_name_p): Even anonymous namespace needs
assembler name.
* mangle.c (mangle_decl): Mangle anonymous namespace types as
"<anon>".
* g++.dg/lto/pr66180_0.C: New testcase.
* g++.dg/lto/pr66180_1.C: New testcase.
