  Keep TIntermSymbol nodes consistent in PruneNoOps
  
  Create new TVariables to change struct declaration qualifiers in
  PruneNoOps so that the node doesn't end up with an inconsistent
  qualifier from the variable.

  // 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.
