Message : Use GetOperatorString when writing GLSL unary built-in calls GetOperatorString is now used when writing GLSL for built-in calls that fall under TIntermUnary. Component-wise not TOperator enum is renamed for consistency. This also cleans up some unnecessary creation of string objects when writing built-in functions.
