It fixes the problem where the execution mode is not valid for the given entry point (`LocalSizeHint` requires `Kernel`) and where an `Input` storage class pointer is incorrectly passed to a function call (there is a restriction on what storage classes are allowed for pointer operands to an `OpFunctionCall`, see "2.16.1. Universal Validation Rules").
