19125 * c-common.c (c_common_nodes_and_builtins): Since variants of

19137 own canonical type.
19138 (build_type_attribute_qual_variant): When building an attribute
19139 variant, its canonical type is the non-attribute variant. However,
19140 if the attributes are target-dependent and they differ, we need to
19141 use structural equality checks for this type.
19142 (build_qualified_type): A qualified type is not equivalent to its
19143 unqualified variant; set the canonical type appropriately.
19144 (build_distinct_type_copy): When building a distinct type from
19145 another type, the new type is its own canonical type.
19146 (build_variant_type_copy): When building a new type variant, we
19147 assume that it is equivalent to the original type.
19148 (build_pointer_type_for_mode): When building a pointer type, also
19149 build a canonical type pointer.
19150 (build_reference_type_for_mode): When building a reference type,
19151 also build a canonical type reference.
19152 (build_index_type): When we can't hash an index type (e.g.,
19153 because its maximum value is negative), the index type requires
19154 structural equality tests.
19155 (build_array_type): Build the canonical form of an array type.
19156 (build_function_type): Function types require structural equality,
19157 because they contain default arguments, attributes, etc.
19158 (build_method_type_directly): Ditto for method types.
