I think it's pretty much impossible.  (We have a similar problem with
hardware watchpoints.)  Several breakpoints can be set to the same
address, in which case a single register can serve all of them, but
deciding that this is the case is tricky at best.

I think the way of throwing an exception and then handling it to
revert to the original state is much more promising.
