Summary Add JSC_functionOverrides=<overrides file> debugging tool

This tool allows us to do runtime replacement of function bodies with alternatives for debugging purposes. For example, this is useful when we need to debug VM bugs which manifest in scripts executing in webpages downloaded from remote servers that we don't control. The tool allows us to augment those scripts with logging or test code to help isolate the bugs.
