Optimize NodeIdentifier reading

NodeIdentifiers are just an alias for QName, which is heavily
reused. This patch adds a secondary cache for interpreting QNames
as NodeIdentifiers, with instance reuse.

This allows us to reduce the number of NodeIdentifier instances,
while not relying on NodeIdentifier.create() for the common lookup
case.
