Centralized all disassembly into static functions in source/Core/Disassembler.cpp.

Added the ability to read memory from the target's object files when we aren't
running, so disassembling works before you run!

Cleaned up the API to lldb_private::Target::ReadMemory().

Cleaned up the API to the Disassembler to use actual "lldb_private::Address"
objects instead of just an "addr_t". This is nice because the Address objects
when resolved carry along their section and module which can get us the 
object file. This allows Target::ReadMemory to be used when we are not 
running.

Added a new lldb_private::Address dump style: DumpStyleDetailedSymbolContext
This will show a full breakdown of what an address points to. To see some
sample output, execute a "image lookup --address <addr>".

Fixed SymbolContext::DumpStopContext(...) to not require a live process in
order to be able to print function and symbol offsets.
