Add atomic method reference map
Less RAM usage and faster than using a normal map with
MethodReference. Speed is faster by avoiding locking and tree
traversal. RAM usage is lower since the map usually had a value
for most method references.
Plan on using for marking methods for dex2dex, storing compiled
methods. Also use the new map for VerifiedMethods (refactoring).
Added test.
