    LoongArch: Fix bug for PR122097.

    When implementing the vector template for copysign, we used vector
    floating-point AND and IOR operations. This allows AND and IOR operands
    to be vector floating-point types. However, the constraint YC does not
    handle vector floating-point constants, resulting in ICE.
