Hi all,

please review the patch which adds
  - a new whitebox method 'deoptimizeFrames' which deoptimizes methods 
which are currently on stack
  - Unsafe.getCompiler methodhotspot-compiler-dev at openjdk.java.net which 
returns 0, 1, 2 if it is interpreted, compiled by c1, c2 accordingly.

jbs: https://bugs.openjdk.java.net/browse/JDK-8028595
testing: jprt + new added test

Thanks,
Igor
