17807 (build_type_attribute_qual_variant): When building an attribute
17808 variant, its canonical type is the non-attribute variant. However,
17809 if the attributes are target-dependent and they differ, we need to
17810 use structural equality checks for this type.
17811 (build_qualified_type): A qualified type is not equivalent to its
17812 unqualified variant; set the canonical type appropriately.
17813 (build_distinct_type_copy): When building a distinct type from
17814 another type, the new type is its own canonical type.
17815 (build_variant_type_copy): When building a new type variant, we
17816 assume that it is equivalent to the original type.
17817 (build_pointer_type_for_mode): When building a pointer type, also
17818 build a canonical type pointer.
17819 (build_reference_type_for_mode): When building a reference type,
17820 also build a canonical type reference.
17821 (build_index_type): When we can't hash an index type (e.g.,
17822 because its maximum value is negative), the index type requires
17823 structural equality tests.
17824 (build_array_type): Build the canonical form of an array type.
17825 (build_function_type): Function types require structural equality,
17826 because they contain default arguments, attributes, etc.
17827 (build_method_type_directly): Ditto for method types.
17828 (build_offset_type): Build the canonical offset type.
