Microtasks, resolved Promises and Observers are handled after the sync
task that caused them, in the order they were generated.
Also simplifies reentrancy handling.

Normally we wouldn't need to send any notifications if the actor was
already destroyed, but it can be a VersionChangeOp which needs to
notify its parent operation (OpenDatabaseOp) about the failure.
So SendFailureResult needs to be called even when the actor was
destroyed. Normal operations redundantly check if the actor was
destroyed in SendSuccessResult and SendFailureResult, therefore it's
ok to call it in all cases here.
CheckedInt propagates the mIsValid in each add operation so that it avoids needing a bunch of code
for the overflow check in each add operation. Additionally, it avoids mismatching parameters
between the computing result and the additional overflow check.
This patch uses CheckedInt to take advantage of those implicit features of it.
