* ipa-utils.h (warn_types_mismatch, odr_or_derived_type_p,
odr_types_equivalent_p): Declare.
(odr_type_p): Use gcc_checking_assert.
(type_in_anonymous_namespace_p) Declare.
(type_with_linkage_p): Declare.
* common.opt (Wlto-type-mismatch): New warning.
* ipa-devirt.c (compound_type_base): New function.
(odr_or_derived_type_p): New function.
(odr_types_equivalent_p): New function.
(add_type_duplicate): Simplify.
(type_with_linkage_p): Add hack to prevent false positives on C types
(type_in_anonymous_namespace_p): Likewise.
* tree.c (need_assembler_name_p): Use type_with_linkage.
