           Summary: [gdb/breakpoints, arm] Failure to set a hw wp while
                    running disables hw wp permanently

  Target Milestone: ---

Arm variant of PR31837 - "[gdb/breakpoints, ppc64le] Failure to set a hw wp
while running disables hw wp permanently".

We can set a hardware watchpoint on arm when the current thread is stopped.

However, we cannot set one if it is running.

And once we tried and failed to because of that reason, we lose the ability=
 to
set one, even if we stop the thread.
