1799 * c-common.c(c_common_nodes_and_builtins): Since variants of

1812 (build_type_attribute_qual_variant): When building an attribute
1813 variant, its canonical type is the non-attribute variant. However,

1817 unqualified variant; set the canonical type appropriately.

1825 also build a canonical type reference.
1826 (build_index_type): When we can't hash an index type (e.g.,
1827 because its maximum value is negative), the index type requires
1828 structural equality tests.
1829 (build_array_type): Build the canonical form of an array type.
1830 (build_function_type): Function types require structural equality,
1831 because they contain default arguments, attributes, etc.
1832 (build_method_type_directly): Ditto for method types.
1833 (build_offset_type): Build the canonical offset type.
1834 (build_complex_type): Build the canonical vector type.
