LGTM, but the macro is kind of ugly and I could live with the code duplication
instead.

PTAL. Now works for native code.

I think there is an issue with deoptimization, below.

http://codereview.chromium.org/8318014/diff/4001/src/hydrogen.cc
File src/hydrogen.cc (right):

http://codereview.chromium.org/8318014/diff/4001/src/hydrogen.cc#newcode5100
src/hydrogen.cc:5100: HValue* function = Pop();
I don't think this is right.  In the unoptimized code, this value is on the
stack until the function returns (e.g., during argument evaluation) and will be
dropped at the return site.

So we need it in the environment in case we deopt during argument evaluation (or
have lazy deopt to the return site of this call).

I think

HValue* function = Top();
...
Drop(argument_count + 1);

is what we need for now.

LGTM.
