Implement ESSL 3.00 shader input/output variable type rules ESSL 3.00 allows a wider variety of types of input/output variables than ESSL 1.00, but there are still specific restrictions on structs, matrices and arrays. Some of the checks need to be implemented twice: once for array syntax where the brackets are after the type, and another time for array syntax where the brackets are after the variable name. This requires fixes to constant folding unit tests which were previously incorrectly using matrix outputs in fragment shaders. New unit tests are added for several of the rules introduced, but some cases are also covered by dEQP.
