Since our expression parser needs to locate areas of memory that are not in use when you have a process that can't JIT code, like core file debugging, the core file process plug-ins should be able to override the Process::GetMemoryRegionInfo(...) function.

In order to make this happen, I have added permissions to sections so that we can know what the permissions are for a given section, and modified both core file plug-ins to override Process::GetMemoryRegionInfo() and answer things correctly.
