Removed old IDL parser and peg parser code.

tools/dom/scripts/go.sh

 #!/bin/bash -x
 #
-#   go.sh [--cached] [systems]
+#   go.sh [systems]
 #
 # Convenience script to generate systems.  Do not call from build steps or tests
 # - call fremontcutbuilder and dartdomgenerator instead. Do not add 'real'
 # functionality here - change the python code instead.
 #
 # I find it essential to generate all the systems so I know if I am breaking
 # other systems.  My habit is to run:
 #
 #   ./go.sh | tee Q
 #
 # I can inspect file Q if needed.
 #
-# If I know the IDL has not changed since the last run, it is faster to run
-#
-#   ./go.sh --cached
-#
 # To generate a subset of systems:
 #
 #   ./go.sh dart2js,htmldart2js
 #
 # The following gives a picture of the changes due to 'work'
 #
 #   git checkout master               # select client without changes
 #   ./go.sh
 #   mv ../generated ../generated0     # save generated files
 #   git checkout work                 # select client with changes
 #   ./go.sh
 #   meld ../generated0 ../generated   # compare directories with too
