Add the ability to process save-core stack-memory-only corefiles
Add a field to the qMemoryRegionInfo packet where the remote stub
can describe the type of memory -- heap, stack. Keep track of
memory regions that are stack memory in lldb. Add a new "--style
stack" to process save-core to request that only stack memory be
included in the corefile.
