Thumb1 ADD/SUB SP instructions are predicable in Thumb2 mode.
Add the predicate operand to the instructions. Update the back end
accordingly where the instructions are used. Restrict the SP operands
to actually only be SP, as otherwise these break assembly parsing for the
normal instruction variants.
