LibJS: Remove direct argument loading since it was buggy

Browse source 
The parser doesn't always track lexical scopes correctly, so let's not
rely on that for direct argument loading.

This reverts the LoadArguments bytecode instruction as well. We can
bring these things back when the parser can reliably tell us that
a given Identifier is indeed a function argument.
