Actually a colleague suggested that rather than adding an offset/setting a bit, we could augment the address with a decorator, e.g. "c"

(lldb) di -s 0x4004f0:c

and this would denote a code bus read. This is perhaps similar to the offset approach, but it does give a more abstract approach to addressing, and could possibly fit in with Greg's previous proposal of:

ResolvedAddress {
   lldb::addr_t addr;
   lldb::segment_t segment;

whereupon "4004f0:c" is parsed into meaning "this address is the addr is the code segment/bus".
