  Implement parsing switch statements
  
  Put in some groundwork for parsing switch statements and case labels in
  the parser, including definitions for IntermNode classes. Intermediate
  functions for adding the statements are stubbed to only generate errors
  for now.
  
  Tested by manually disabling shading language version checks for switch
  in a Chromium build and checking that the expected errors are generated.
