Fix perf bugs with multiple breakpoints
Visual Studio often ends up with duplicate breakpoints (even duplicates of breakpoints that were set at a particular code address, which makes no sense) and these duplicate breakpoints significantly harm single-stepping performance, add/remove breakpoint performance, closing solutions (60 second solution shut down time was shown through xperf profiling to be due to breakpoints).
The cause of the duplicate breakpoints should be fixed, and the performance problems from having many breakpoints must be fixed.

Yes, please! One of the day-to-day issues, Breakpoints pile up, and deleting them all the time is a real hassle.
