Replace shader's stage variables whose types are array or matrix with scalars/vectors. For example, ``` Before: %foo = OpVariable %_ptr_Output__arr_v2float_uint_4 Output After: %foo = OpVariable %_ptr_Output_v2float Output %foo_0 = OpVariable %_ptr_Output_v2float Output %foo_1 = OpVariable %_ptr_Output_v2float Output %foo_2 = OpVariable %_ptr_Output_v2float Output ```
