[issue43563] Use dedicated opcodes to speed up calls/attribute lookups with super() as receiver

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

Currently, super() is decoupled from the core language.  It is just a builtin that provides customized attribute lookup.  This PR makes super() more tightly integrated with the core language, treating it as if it were a keyword and part of the grammar.  Also note, users can currently create their own versions of super(), shadowing the builtin super().
