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=bitcast: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".
