Rework arguments object. (#1401)

Browse Source 
Instead of allocating a helper object, argument names are appended right
after the arguments objects. This reduces memory consumption and improve
performance as well. In the future this could be further improved by a
bitfield, but that would require a reference to the byte code which
might increase memory consumption in a few corner cases.
