30002 * c-common.c (c_common_nodes_and_builtins): Since variants of

30010 * stor-layout.c (layout_type): When we don't know the
30011 alignment of a type for which we're building an array, we end up
30012 guessing wrong, so make the type require structural equality.

30014 own canonical type.
30015 (build_type_attribute_qual_variant): When building an attribute
30016 variant, its canonical type is the non-attribute variant. However,
30017 if the attributes are target-dependent and they differ, we need to
30018 use structural equality checks for this type.
30019 (build_qualified_type): A qualified type is not equivalent to its
30020 unqualified variant; set the canonical type appropriately.
30021 (build_distinct_type_copy): When building a distinct type from
30022 another type, the new type is its own canonical type.
30023 (build_variant_type_copy): When building a new type variant, we
30024 assume that it is equivalent to the original type.
30025 (build_pointer_type_for_mode): When building a pointer type, also
30026 build a canonical type pointer.
30027 (build_reference_type_for_mode): When building a reference type,
30028 also build a canonical type reference.
30029 (build_index_type): When we can't hash an index type (e.g.,
30030 because its maximum value is negative), the index type requires
30031 structural equality tests.
30032 (build_array_type): Build the canonical form of an array type.
30033 (build_function_type): Function types require structural equality,
30034 because they contain default arguments, attributes, etc.
30035 (build_method_type_directly): Ditto for method types.
30036 (build_offset_type): Build the canonical offset type.
