Description: 
We have two collections, those store lock modes:
{code}
HeapLockManager.WaiterImpl#locks
HeapLockManager.WaiterImpl#intendedLocks
{code}
That is done for convenient way to implement all lock manager requirement. But 
for optimization, we can do this through _BitSet_. The redesign is possible 
because we have predefined lock modes (_LockMode_) and attempts to accesses to 
the modes are bounded. The amount of attempts significantly less than MaxInt 
value.
The optimization allows using less memory for lock on each entry.
