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; })();

Field layout in class Arguments is incompatible w\ 64-bit archs.

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.

V8 can clear exception pending message, when should not do this.

The case:
v8::TryCatch try_catch;
CompileRun(try { CEvaluate('throw 1;'); } finally {});
CHECK(try_catch.HasCaught());
CHECK(!try_catch.Message().IsEmpty());

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

Support external startup data in V8.

[Retry of crrev.com/293993021, which caused problems with 'ninja all' in Chromium. First patch set if a clean apply
of crrev.com/293993021. Subsequent sets are the actual fix
for that issue.]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.
