This doesn't need to be a template, since a type of Arguments is always
v8::Handle<v8::Value>.

I cannot consider other use cases of this helper method, so I might want to just
write the logic inline in CodeGeneratorV8.pm (rather than creating a helper
method).

Inlining this might lead to some code size increase, since it would be repeated
a few places.  For now I removed the template argument, and moved the code to
the CPP file.
