Fix code generation of binary instructions with the r21 option
OTP 22 extends the binary instructions to support a Y register destination. When giving an option to compile for an earlier release, make sure that binary instructions don't use a Y register destination, by rewriting the binary instructions to use an X register destination and adding a `move` instruction to move the value to the Y register.
