This is typically used after the process calls exec, or anytime the architecture of the target changes.

Parameters

[in] arch If valid, check the module in each breakpoint to make sure they are compatible, otherwise, ignore architecture.

added says whether the module was loaded or unloaded.

Parameters

[in]	module_list	The module list that has changed.
[in]	load	true if the modules are loaded, false if unloaded.
[in]	delete_locations	If load is false, then delete breakpoint locations when when updating breakpoints.
