RFR 8228532: Shenandoah: Implement SBSA::try_resolve_jobject_in_native()

[Zhengyu Gu]

Shenandoah needs to take slow path when resolving jobject during 
evacuation phase, to ensure it resolves to-space oops.

Bug: https://bugs.openjdk.java.net/browse/JDK-8228532
Webrev: http://cr.openjdk.java.net/~zgu/JDK-8228532/webrev.00/index.html

Test:
   hotspot_gc_shenandoah (fastdebug and release) on Linux x86_64 and 
aarch64.


Thanks,
