    Simplify 'ExtBits' in the lexer
    
    The main change is to export 'ExtBits' instead of defining/exporting a
    bunch of boilerplate functions that test for a particular 'ExtBits'.
    In the process, I also
    
      * cleaned up an unneeded special case for 'ITstatic'
      * made 'UsePosPrags' another variant of 'ExtBits'
      * made the logic in 'reservedSymsFM' match that of 'reservedWordsFM'
    
    Test Plan: make test
