Do you mean ARMTargetMachine::getSubtargetImpl (https://github.com/llvm-mirror/llvm/blob/master/lib/Target/ARM/ARMTargetMachine.cpp#L305) ?
It seems like that function is only used by llc (and not llvm-as for example) and at that stage it is too late to add thumb-mode, because llc operates on a single module with a single target triple.
