TranslateArgs - Create a new derived argument list for any argument translations this ToolChain may wish to perform, or 0 if no tool chain specific translations are needed.

If DeviceOffloadKind is specified the translation specific for that offload kind is performed.

Parameters
BoundArch- The bound architecture name, or 0.
DeviceOffloadKind- The device offload kind used for the translation.
