24413 * c-common.c (c_common_nodes_and_builtins): Since variants of

24425 own canonical type.
24426 (build_type_attribute_qual_variant): When building an attribute
24427 variant, its canonical type is the non-attribute variant. However,
24428 if the attributes are target-dependent and they differ, we need to
24429 use structural equality checks for this type.
24430 (build_qualified_type): A qualified type is not equivalent to its
24431 unqualified variant; set the canonical type appropriately.
24432 (build_distinct_type_copy): When building a distinct type from
24433 another type, the new type is its own canonical type.
24434 (build_variant_type_copy): When building a new type variant, we
24435 assume that it is equivalent to the original type.
24436 (build_pointer_type_for_mode): When building a pointer type, also
24437 build a canonical type pointer.
24438 (build_reference_type_for_mode): When building a reference type,
24439 also build a canonical type reference.
24440 (build_index_type): When we can't hash an index type (e.g.,
24441 because its maximum value is negative), the index type requires
24442 structural equality tests.
24443 (build_array_type): Build the canonical form of an array type.
24444 (build_function_type): Function types require structural equality,
24445 because they contain default arguments, attributes, etc.
24446 (build_method_type_directly): Ditto for method types.
