Details:
    Building on support in trunk just added for 'cast' and 'is', this  
change
    allows these keywords to be passed through and emitted as is to  
the third
    party compiler.

    SWF9Generator.java: intercept JavascriptGenerator implementation  
of 'cast'
    and 'is' so they are not handled directly within the compiler, but  
left alone.

    SWF9ParseTreePrinter.java: added knowledge of 'cast' and 'is'  
operators
    to emit these as is.


Tests:
  1)  Imported a few tests that use cast/is from lztest-class-impl.lzx  
into
    a private copy of LzNode.js:

   var xf1 = ( (new Sundae()) cast Vanilla instanceof Number );
   var xt1 = ( (new Number()) cast Object instanceof Number );
   var xf2 = ( (new Sundae()) cast Vanilla is Number );
   var xt2 = ( (new Number()) cast Object is Number );

    (along with modified versions of Sundae and Vanilla).
    Verified that these compiled and emitted the same in the output  
files
    fed to the third party compiler.

  2)  did smoketest
