* breakpoint.c (create_longjmp_master_breakpoint): Check if probe
interface can evaluate arguments. Fallback to the old mode if it
cannot.
(create_exception_master_breakpoint): Likewise.
* elfread.c (elf_can_evaluate_probe_arguments): New function.
(struct sym_probe_fns elf_probe_fns): Export function above to the
probe interface.
* probe.c (can_evaluate_probe_arguments): New function.
* probe.h (struct probe_ops) <can_evaluate_probe_arguments>: New
function pointer.
(can_evaluate_probe_arguments): New function prototype.
* solib-svr4.c (svr4_create_solib_event_breakpoints): Check if
probe interface can evaluate arguments. Fallback to the old mode
if it cannot.
* stap-probe.c (stap_get_probe_argument_count): Check if probe
interface can evaluate arguments. Warning the user if it cannot.
(stap_can_evaluate_probe_arguments): New function.
(struct probe_ops stap_probe_ops): Export function above to the
probe interface.
* symfile.h (struct sym_probe_fns) <can_evaluate_probe_arguments>:
New function pointer.
