I've created #140669 that adds a temporary support for CTC in lite mode.

Reading ARM manual, all conditional branches have the following statement in their description "<instruction> provides a hint that this is not a subroutine call or return". Not sure what are the consequences if any when the instruction is used as a tail call. Regular branch `B` has the same comment attached to it.
