    rs6000: optimize moving to sf from highpart di

    Currently, we have the pattern "movsf_from_si2" which was trying
    to support moving high part DI to SF.

    But current pattern only accepts "ashiftrt":
    XX:SF=3Dbitcast:SF(subreg(YY:DI>>32),0), but actually "lshiftrt" should
    also be ok.
    And current pattern only supports BE.

    Here, updating the pattern to support BE and "lshiftrt".
