control to the user anyway. This was put in to handle monitors that would say there was no stop reason when you first attached to them. But it broke the case where you hit a thread specific breakpoint on many threads, but NOT the one specified in the breakpoint. I work around this by only doing the junky override when the StopID is 0 - i.e. on first attach. This commit also adds a test for thread specific breakpoints. llvm-svn: 199290
