[Bug]: Debugger pretty printers don't work with multilocale builds

[jabraham17]

The LLDB pretty printers don't work well with distributed code. This is because instead of wide pointers.

The pretty printer works by inspecting the data structure's and type info to print a custom output. For example, with arrays, to determine the bounds of the domain we inspect myArr->_instance->dom->data->ranges. But with distributed code, _instance and data (and maybe others?) are wide pointers, which means we need to traverse myArr->_instance->addr->dom->data->addr->ranges.

Note that this assume the data is local. Handling printing remote data is much harder and probably out of scope for supporting right now

Thinking about it more, I think handling the remote data might be solvable by calling chpl_comm_get from the debugger. This is a little tricky because we then need to allocate space for the data and give it the proper types/sizes, and I'm not sure how far we can push lldb's ability to eval expressions
