RFR(S) 8238782: Cleanup Deoptimization::deoptimize(): remove unused RegisterMap argument and don't update RegisterMap in callers if UseBiasedLocking is enabled

[Reingruber, Richard]

Hi,

I would like to do a small clean-up removing the unused parameter "map" from
Deoptimization::deoptimize(JavaThread* thread, frame fr, RegisterMap *map, DeoptReason reason).

Additionally the callers are changed to use a non-updating RegisterMap to iterate the stack
frames. The updating RegisterMap was needed only for revoking biases in
Deoptimization::deoptimize(), and since JDK-8226705 this isn't done in deoptimize() anymore[1][2][3].

So please review

Webrev: http://cr.openjdk.java.net/~rrich/webrevs/8238782/webrev.0/
Bug:    https://bugs.openjdk.java.net/browse/JDK-8238782

Testing: JCK and JTREG tests, also in Xcomp mode with fastdebug and release builds on all platforms.

Thanks, Richard.
