re PR c++/35319 (ICE throwing fixed-point types)
PR c++/35319
* mangle.c (write_builtin_type): Add mangling for decimal floating
point and fixed point types.
(write_type): Pass FIXED_POINT_TYPE along.
* cp-demangle.c (cplus_demangle_type): Support fixed-point types.
(d_print_comp, d_dump): Likewise.
