[ignition] Collect feedback for super constructor calls.

[ignition] Collect feedback for super constructor calls.

In order to optimize super constructor calls with ES6 classes, we need
some feedback for both the JSCallConstruct and the resulting JSCreate
nodes in TurboFan. Both already optimize perfectly when the see nodes
with JSFunction constants, so utilizing the existing CallIC machinery
here, enables us to optimize the super constructor calls right now w/o
a lot of effort.

Note that there are probably better ways to track this information,
for example we could do some tracking on the constructor functions;
this will however require serious changes in TurboFan and the runtime,
and would block progress on more important tasks.

Hey Mythri,

Here's a simple one-liner to enable feedback on super constructor calls, for
Ignition only *yay*! :-)
Please take a look.

Thanks,
Benedikt

Great. Ignition going ahead of FCG in collecting feedback. :) LGTM.
