[8u40] Request for approval: Batch integration of JEP 210: LambdaForm Reduction and Caching

[Vladimir Ivanov]

Hello,

Please, approve integration of JEP 210 [1] into 8u-dev.
All the changes have passed review for 9. Integration into 9 is pending. 
There's an exception to integrate into 8u40 separately.

The changes apply almost cleanly (need some trivial adjustments [2]).
