Improve 1010102 blend precision

Making sure we extend 1010102 to the full 16 bit range
fixes 51 of the 53 failures found in ToT dEQP-VK.*a2b10*

Also added a utility function to OR all elements of an
int vector, which allows us to use more vector operations
(as opposed to scalar) while improving the readability.
