Message:

Add support to throw OOM if MarkedArgumentBuffer may overflow.

Reviewed by Saam Barati.

Source/JavaScriptCore:

The test for overflowing a MarkedArgumentBuffer will run for a ridiculously long
time, which renders it unsuitable for automated tests. Instead, I've run a
test manually to verify that an OutOfMemoryError will be thrown when an overflow
occurs.

The MarkedArgumentBuffer's destructor will now assert that the client has indeed
checked for an overflow after invoking methods that may result in an overflow i.e.
the destructor checks that MarkedArgumentBuffer::hasOverflowed() has been called.
This is only done on debug builds.
