// PruneNoOps.h: The PruneNoOps function prunes:
//   1. Empty declarations "int;". Empty declarators will be pruned as well, so for example:
//        int , a;
//      is turned into
//        int a;
//   2. Literal statements: "1.0;". The ESSL output doesn't define a default precision for float,
//      so float literal statements would end up with no precision which is invalid ESSL.
//   3. Statements after discard, return, break and continue.
//   4. Switch statements over a constant, where no case matches the constant
