There is no need for the requirement for conditional-move data input
operands to be stricter for T-Head targets than for short forward branch
targets and limit them to registers only. They are keyed according to
the `sfb_alu_operand' predicate, which lets certain constants through.
Such constants are already forced into a register for the `cons' operand
in the analogous short forward branch case and we can force them for the
`alt' operand and T-Head as well. This enables more opportunities for a
branchless sequence to be produced.

OK.
