libphobos: Print stacktrace before terminating program due to uncaught exception.
By default, D run-time has a top level exception handler to catch
anything that was uncaught by user code. However when the
`rt_trapExceptions' flag is cleared, this handler would not be enabled,
and this termination would occur, aborting the program, but without any
information about the exception.
libphobos/ChangeLog:
* libdruntime/gcc/deh.d (_d_print_throwable): Declare.
(_d_throw): Print stacktrace before terminating program due to
uncaught exception.
