+ Resume every hart.
+
+ This function works fine when using multiple gdb sessions, but the
+ caller must be careful when using it nonetheless. gdb's behavior is to
+ not set breakpoints until just before the hart is resumed, and then
+ clears them as soon as the hart halts. That means that you can't set
+ one software breakpoint, and expect multiple harts to hit it. It's
+ possible that the first hart completes set/run/halt/clear before the
+ second hart even gets to resume, so it will never hit the breakpoint.
