// Breakpoints in LLDB can have names added to them which are kind of like
// labels or categories. All breakpoints that are set through the IDE UI get
// sent through the various VS code 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.
