glsl: Fix broken constant expression handling for <, <=, >, and >=.
We were looping over all the vector components, but only dealing with
the first one. This was masked by the fact that constant expression
handling on built-ins went through custom code for the lessThan()
/function/ rather than the ir_binop_less expression operator.
NOTE: This is a candidate for all release branches.
