[es6] Super call in arrows and eval

[es6] Super call in arrows and eval

This splits the SuperReference AST node into SuperPropertyReference and
SuperCallReference. The super call reference node consists of three
unresolved vars to this, new.target and this_function. These gets
declared when the right function is entered and if it is in use. The
variables gets assigned in FullCodeGenerator::Generate.

This is a revert of the revert 88b1c9170a0293cbcc8bdaf57fbe12744b48d7e8

Push this_function earlier

PTAL

Patchset 1 is a revert of the revert.

Patchset 2 moves the push of this_function to earlier since SetVar overwrites
the registry.

This fixes the test failures. This does not handle the issues I discovered
related to eval and lazy parsing. I will take care of that in a followup CL.
