  Declare specialization constants in the AST
  
  A new qualifier (EvqSpecConst) is added so that specialization constants
  can be declared in tree.
  
  This enables TVariable references to specialization constants to be
  validated, which were in fact invalid as every reference declared a new
  variable.  That is fixed.
