Change BC to an RX-a instruction format

Technically this is an RX-b instruction however we currently do not have a proper class for such instructions and we generate the `BC` instruction as part of z/OS linkage in which we use a real register to generate the mask. Assertions later on prevent us from doing this if the `BC` instruction is properly marked as an RX-a instruction. Signed-off-by: Filip Jeremic <[email protected]>
