    RISC-V: drop FCVT.Q.L{,U} forms with rounding mode operand
   =20
    Like FCVT.D.W{,U} and FCVT.Q.W{,U} these also are unaffected by rounding
    mode, and hence allowing for a respective operand is bogus. (Otherwise
    MASK_RM should also be used in the match field for the respectively oth=
er
    forms.)
