translator: Fix validation sometimes modifying builtins. When validating some shaders with out-of-bounds array indexes, we would write the sanitized index into the global symbol table. We would then overwrite a wrong value for the builtin. This fixes the WebGL test extensions/webgl-draw-buffers-max-draw-buffers. Also mark const on as many uses ConstantUnion as we can.
