Added the ability for SBTarget to resolve load addresses (convert lldb::addr_t values into resolved SBAddress objects). These SBAddress objects can then be used to resolve a symbol context using "lldb::SBSymbolContext ResolveSymbolContextForAddress (const lldb::SBAddress& addr, uint32_t resolve_scope);".
