If possible, get rid of kInvalidStrictFlag.
If the problem is the assert, it's because we cast some integer to
StrictModeFlag, and then we should really test the value *before* casting it
(which is what we mean, and it's also not undefined behavior). If a value
already has the enum type, we shouldn't need to test.
