[builtins] Introduce specialized Call/CallFunction builtins.

[builtins] Introduce specialized Call/CallFunction builtins.

Introduce receiver conversion mode specialization for the Call and
CallFunction builtins, so we can specialize the builtin functionality
(actually an optimization only) based on static information from the
callsite (this is basically a superset of the optimizations that were
available with the CallFunctionStub and CallICStub, except that these
optimizations are correct now).

This fixes a regression introduced by the removal of CallFunctionStub,
for programs that call a lot.

Hey Yang,

Here's the patch that introduces specialization (with ConvertReceiverMode) for
Call/CallFunction builtins, that I told you about earlier. More or less
straightforward threading off the mode.
Please take a look.

Thanks,
Benedikt
