Turn off GC_LOOP_ON_ABORT functionality if GC compiled with NO_DEBUGGING

* misc.c (looping_handler, installed_looping_handler): Do not define
if NO_DEBUGGING.
* misc.c (maybe_install_looping_handler): Define as an empty macro if
NO_DEBUGGING.
* misc.c (GC_on_abort): Do not test "GC_LOOP_ON_ABORT" environment
variable if GC_LOOP_ON_ABORT.
