Summary: This checkin sends an MI event when a module is loaded that causes a pending breakpoint to bind to it's real address in the target. This allows breakpoints to be set before the process is launched, and the target address of the BP to be discovered when the module loads, prior to the breakpoint being hit. Patch from chuckr@microsoft.com Test Plan: I ran the check-lldb target with and without this patch and saw no change. I am unsure of how to write an MI specific test for this because the new event is buried in module load events. Here is an example (the new event is in bold): ``` (gdb) -file-exec-and-symbols a.out ^done (gdb)
