They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.
This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).

r18790 "Remove ArrayPush from the custom call generators, and instead call directly to the handler in crankshaft.", and

For causing crashes on Canary.

Our testing infrastructure uses exceptions to indicate
errors. assertUnreachable therefore throws an exception to indicate
that it was reached. Therefore, it cannot be used to check that an
exception was thrown using the pattern:
try {
shouldThrow();
assertUnreachable();
} catch(e) {
}
Such a test will always pass because assertUnreachable will throw an
exception if shouldThrow does not.

Encapsulate the helper functions in mjsunit.js.
Now only exposes the exception class and the assertXXX functions.
Make assertEquals use === instead of ==.
This prevents a lot of possiblefalse positives in tests, and avoids
having to do assertTrue(expected === actual) when you need it.
Fixed some tests that were either buggy or assuming == test.
