  Identify functions by unique id in BuiltInFunctionEmulator
  
  Now that unique ids of all builtins are compile-time constants, we can
  use them to look up functions in BuiltInFunctionEmulator. This is
  simpler than using a custom struct with the name and parameters for
  identifying functions.
  
  This requires that we store a reference to a TFunction in those
  TIntermUnary nodes that were created based on a function.
  
  This decreases shader_translator binary size by about 6 KB on Windows.
