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

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.

Reported by Yang Rong.
