  Make angle::Result an enum.
  
  This moves away from a class type to a value type. This should improve
  performance when using angle::Result as a return value. Previously the
  generated code would return a pointer instead of a value.
  
  Improves performance in the most targeted microbenchmark by 10%. In
  more realistic scanarios it will have a smaller improvement. Also
  simplifies the class implementation and usage.
  
  Includes some unrelated code generation changes.
