This is one step further towards the removal of all these macros.
gdb/ChangeLog:
* gdbtypes.h (struct type) <fixed_point_info, set_fixed_point_info>:
New methods.
(INIT_FIXED_POINT_SPECIFIC): Adjust.
(TYPE_FIXED_POINT_INFO): Delete macro.
(allocate_fixed_point_type_info): Change return type to void.
* gdbtypes.c (copy_type_recursive): Replace the use of
TYPE_FIXED_POINT_INFO by a call to the fixed_point_info method.
(fixed_point_scaling_factor): Likewise.
(allocate_fixed_point_type_info): Change return type to void.
Adjust implementation accordingly.
* dwarf2/read.c (finish_fixed_point_type): Replace the use of
TYPE_FIXED_POINT_INFO by a call to the fixed_point_info method.
