  // labels or categories. All breakpoints that are set through the IDE UI get
  // sent through the various DAP set*Breakpoint packets, and these
  // breakpoints will be labeled with this name so if breakpoint update events
  // come in for breakpoints that the IDE doesn't know about, like if a
  // breakpoint is set manually using the debugger console, we won't report any
  // updates on them and confused the IDE. This function gets called by all of
  // the breakpoint classes after they set breakpoints to mark a breakpoint as
  // a UI breakpoint. We can later check a lldb::SBBreakpoint object that comes
  // in via LLDB breakpoint changed events and check the breakpoint by calling
  // "bool lldb::SBBreakpoint::MatchesName(const char *)" to check if a
  // breakpoint in one of the UI breakpoints that we should report changes for.
