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 88b1c9170a

When compiling on a laptop I like to concatenate the small test files.
This makes a big difference to compile times. These changes make that
easier.

Also support patterns in ``for (var p in/of ...)``
This CL extends the rewriting we used to do for ``for (let p in/of...)`` to
``for (var p in/of ...)``. For all for..in/of loop declaring variable,
we rewrite
for (var/let/const pattern in/of e) b
into
for (x' in/of e) { var/let/const pattern = e; b }
This adds a small complication for debugger: for a statement
for (var v in/of e) ...
we used to have
var v;
for (v in/of e) ...
and there was a separate breakpoint on ``var v`` line.
This breakpoint is actually useless since it is immediately followed by
a breakpoint on evaluation of ``e``, so this CL removes that breakpoint
location.
Similiraly, for let, it used to be that
for (let v in/of e) ...
became
for (x' in/of e) { let v; v = x'; ... }
``let v``generetaed a useless breakpoint (with the location at the
loop's head. This CL removes that breakpoint as well.

This patch:
- Refactors Parser::ParseVariableDeclarations
- Introduces Parser::PatternMatcher class
- Implements matching a single variable pattern
- Implements rudimentary matching against object literal pattern
as a proof of concept
