Hi

The last operand of instruction sqdmulh can only be low fp registers,
so we should use constraint "x". But the intrinsic functions use "w".
This patch fixed the constrains in these intrinsics.

Passed dejagnu test on aarch64 qemu. OK for trunk, 4.9 and 4.8?

thanks

        the last operand's constraint.
        (vqdmulh_n_s32): Likewise.
