Optimize load double into xmm with zero_extend
"movq" should used to load double into xmm register with zero_extend:
(set (reg:V2DF 90)
(vec_concat:V2DF (reg/v:DF 88 [ d ])
(const_double:DF 0.0 [0x0.0p+0])))
Unlike "movsd", which only works with load from memory, "movq" works
with both memory and xmm register.

replace %vmovsd with "%vmovq".
(vec_concatv2df): Likewise.
