that use the Mach::linkedit_data_command type for the load commands that are
currently used in the MachOObjectFile constructor.
This contains the missing checks for LC_DATA_IN_CODE and
LC_LINKER_OPTIMIZATION_HINT load commands and the fields for the
Mach::linkedit_data_command type. Checking for other load commands that
use this type will be added later.
Also fixed a couple of places that was using sizeof(MachOObjectFile::LoadCommandInfo)
that should have been using sizeof(MachO::load_command).
