RFR: 8156552: [JVMCI] remove final and stable field handling from ConstantReflectionProvider

[Roland Schatz]

Hi,

Please review:
http://cr.openjdk.java.net/~rschatz/JDK-8156552/webrev.00/
https://bugs.openjdk.java.net/browse/JDK-8156552

This is pure removal of a few methods from the 
ConstantReflectionProvider interface, their implementation, and their tests.
All jvmci jtreg tests pass.

Thanks,
Roland
