Hi,
this patch fixes ICE when we output ODR violation warning compiling
cactusBSSN. As indicated in PR, i think the warning is wrong and we need
to teach C++ FE to not consider the type in question as anonymous
namespace.

Regtested x86_64-linux. Comitted as obvious.

	PR lto/91222
	* ipa-devirt.c (warn_types_mismatch): Compare indentifiers
	than INDENTIFIER_POINTER.
