10640 * c-common.c (c_common_nodes_and_builtins): Since variants of

10652 own canonical type.
10653 (build_type_attribute_qual_variant): When building an attribute
10654 variant, its canonical type is the non-attribute variant. However,
10655 if the attributes are target-dependent and they differ, we need to
10656 use structural equality checks for this type.
10657 (build_qualified_type): A qualified type is not equivalent to its
10658 unqualified variant; set the canonical type appropriately.
10659 (build_distinct_type_copy): When building a distinct type from
10660 another type, the new type is its own canonical type.
10661 (build_variant_type_copy): When building a new type variant, we
10662 assume that it is equivalent to the original type.
10663 (build_pointer_type_for_mode): When building a pointer type, also
10664 build a canonical type pointer.
10665 (build_reference_type_for_mode): When building a reference type,
10666 also build a canonical type reference.
10667 (build_index_type): When we can't hash an index type (e.g.,
10668 because its maximum value is negative), the index type requires
10669 structural equality tests.
10670 (build_array_type): Build the canonical form of an array type.
10671 (build_function_type): Function types require structural equality,
10672 because they contain default arguments, attributes, etc.
10673 (build_method_type_directly): Ditto for method types.
10674 (build_offset_type): Build the canonical offset type.
