Optimize (a & b) | (c & ~b) to vpternlog instruction.
Also optimize below 3 forms to vpternlog, op1, op2, op3 are
register_operand or unary_p as (not reg)
A: (any_logic (any_logic op1 op2) op3)
B: (any_logic (any_logic op1 op2) (any_logic op3 op4)) op3/op4 should
be equal to op1/op2
C: (any_logic (any_logic (any_logic:op1 op2) op3) op4) op3/op4 should
be equal to op1/op2
