Change breakpoints to use value_ref_ptr
Now that value_ref_ptr exists, it is possible to simplify breakpoint
and bpstat memory management by using a value_ref_ptr rather than
manually handling the reference counts.
gdb/ChangeLog
2018-04-06 Tom Tromey <tom@tromey.com>
* value.c (release_value): Update.
* breakpoint.h (struct watchpoint) <val>: Now a value_ref_ptr.
(struct bpstats) <val>: Now a value_ref_ptr.
* breakpoint.c (update_watchpoint, breakpoint_init_inferior)
(~bpstats, bpstats, bpstat_clear_actions, watchpoint_check)
(~watchpoint, print_it_watchpoint, watch_command_1)
(invalidate_bp_value_on_memory_change): Update.
