Instead of marking the comparison instruction itself as Uint32, we
look at its arguments. This is more consistent what HChange does.

CEvaluate is native call. Last check is not passed without patch. Patch contains test TryCatchFinallyStoresMessageUsingTryCatchHandler with more details.

Since r21232, maps are now a non-power-of-two size and thus don't fit
evenly into a page.  No test case, as it is somewhat difficult to get
this condition to trigger.  It is possible with this case, however:

    var result;

    (function() {
        for (var i = 0; i < 1e7; i++) {
            result = (function*() { yield 1; })();
            result.foo = 1;
        }
    })();

The length_ field must be defined as intptr_t rather than int.  This is
due to the fact that we place native argc/argv values into stack slots
(via SetFrameSlot) and then interpret the slots as a an instance of
Arguments class.

Little endian architectures get 'lucky' that the layout happens to work
with implicit padding.  Big endian is not as lucky.

See Runtime_ArrayConstructor for an example.
