8005976: Break out AccessSpecializer into one pass before CodeGenerator instead of iterative applications from CodeGenerator Summary: Now scope and slot information is guaranteed to be fixed AND NOT CHANGE before CodeGeneration. We want to keep it that way to build future type specializations and bring all type work out of CodeGenerator. Reviewed-by: attila, hannesw

# The purpose of this script is to provide a large amount of IR/bytecode from a known
# application to be diffed against the same output with a different Nashorn version.
# That way we can quickly detect if a seemingly minute change modifies a lot of code,
# which it most likely shouldn't. One example of this was when AccessSpecializer was
# moved into Lower the first time, it worked fine, but as a lot of Scope information
# at the time was finalized further down the code pipeline it did a lot fewer callsite
# specializations. This would have been immediately detected with a before and after 
# diff using the output from this script.
