15568 (HWS, EOID): New shorthand.
15569 (IWORD): Add a couple more types.
15570 (yylex): Add a setup stanza. Remove the complex rules for
15571 detecting GTY'ed types and typedefs; replace with simple
15572 keyword detectors. Adjust everything for the changed
15573 definition of yylval. Ignore all pp-directives, not just #define.

15665 * gengtype-lex.l: Adjust for removal of second argument to
15666 create_scalar_type. Use yylval.s instead of yylval.t when
15668 * gengtype-yacc.y: Type of SCALAR is string. Call
15669 create_scalar_type from type:SCALAR rule. Adjust for removal of
15670 second argument to create_scalar_type.
15672 * vec.h: Remove all #if IN_GENGTYPE blocks.
15673 Add comment saying that changes may require adjustments to gengtype.

24835 * c-common.c (c_common_nodes_and_builtins): Since variants of

24848 (build_type_attribute_qual_variant): When building an attribute
24849 variant, its canonical type is the non-attribute variant. However,
24850 if the attributes are target-dependent and they differ, we need to
24851 use structural equality checks for this type.
24852 (build_qualified_type): A qualified type is not equivalent to its
24853 unqualified variant; set the canonical type appropriately.
24854 (build_distinct_type_copy): When building a distinct type from
24855 another type, the new type is its own canonical type.
24856 (build_variant_type_copy): When building a new type variant, we
24857 assume that it is equivalent to the original type.
24858 (build_pointer_type_for_mode): When building a pointer type, also
24859 build a canonical type pointer.
24860 (build_reference_type_for_mode): When building a reference type,
24861 also build a canonical type reference.
24862 (build_index_type): When we can't hash an index type (e.g.,
24863 because its maximum value is negative), the index type requires
24864 structural equality tests.
24865 (build_array_type): Build the canonical form of an array type.
24866 (build_function_type): Function types require structural equality,
24867 because they contain default arguments, attributes, etc.
24868 (build_method_type_directly): Ditto for method types.
