Mythri 5a68df2ab5 Remove support for unused compile options. 
We don't use parser caches anymore and request code caches
explicitly using ScriptCompiler::CreateCodeCache. Hence
removing the support for both parser cache and code cache options.
They are still retained in CompileOptions for backwards
compatibility. Apart from the api.cc, no other part should see
this option.
