re PR c/24255 (__transparent_union__ mishandled)
PR c/24255
* tree.h (DECL_TRANSPARENT_UNION): Remove.
* function.c (assign_parm_find_data_types): Don't support it.
* print-tree.c (print_node): Likewise.
* c-common.c (handle_transparent_union_attribute): Likewise.
Use build_duplicate_type.
* tree-inline.c (remap_type_1): Split out of remap_type;
properly remap aggregate fields.
(build_duplicate_type): New.
* doc/extend.texi (Variable Attributes): Remove documentation
for transparent_union.
