19513 (build_type_attribute_qual_variant): When building an attribute
19514 variant, its canonical type is the non-attribute variant. However,
19515 if the attributes are target-dependent and they differ, we need to
19516 use structural equality checks for this type.
19517 (build_qualified_type): A qualified type is not equivalent to its
19518 unqualified variant; set the canonical type appropriately.
19519 (build_distinct_type_copy): When building a distinct type from
19520 another type, the new type is its own canonical type.
19521 (build_variant_type_copy): When building a new type variant, we
19522 assume that it is equivalent to the original type.
19523 (build_pointer_type_for_mode): When building a pointer type, also
19524 build a canonical type pointer.
19525 (build_reference_type_for_mode): When building a reference type,
19526 also build a canonical type reference.
19527 (build_index_type): When we can't hash an index type (e.g.,
19528 because its maximum value is negative), the index type requires
19529 structural equality tests.
19530 (build_array_type): Build the canonical form of an array type.
19531 (build_function_type): Function types require structural equality,
19532 because they contain default arguments, attributes, etc.
19533 (build_method_type_directly): Ditto for method types.
19534 (build_offset_type): Build the canonical offset type.
