* s390-tdep.c (struct frame_extra_info): new member:
'stack_bought_valid'.
(s390_get_frame_info): Set fextra_info->stack_bought_valid if we
initialize fextra_info->stack_bought.
(s390_frameless_function_invocation): Don't trust the value of
fextra_info_ptr->stack_bought unless
fextra_info->stack_bought_valid is set.
