[Beignet] [PATCH] GBE: fixed one bug for vector relational builtin functions.

[Zhigang Gong]

For most vector relational builtin functions, we need to
return -1 if the element result is true, return 0 if the element
result is 0. So we can simply put a - in front of the scalar
version of function for each element.
