Drop stack-locals from ScopeInfo

For now we keep params since NewSloppyArguments uses it to figure out how to structure the arguments object. We should be able to only keep params in case we have a special case though. E.g., leaf functions with no duplicate parameters don't need special treatment. Or we simply encode the parameter index for each context slot. (I'm not sure duplicates need special treatment.)
