Remove obsolete 'arguments' local variable handling.

Remove obsolete 'arguments' local variable handling.

This removes special casing for the 'f.arguments' property accessor. Any
local 'arguments' variable should not be allowed to influence the value
returned by the indirect 'f.arguments' property. That property creates a
new object with a separate identity everytime it is read. This is by now
consistent with other browsers.
