[11] RFR(S): 8200290: Scratch buffer creation fails with "assert(!current_thread_in_native()) failed: must not be in native" on SPARC

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8200290
http://cr.openjdk.java.net/~thartmann/8200290/webrev.00/

Similar to JDK-8193699, the code in MacroAssembler::constant_oop_address() needs to be changed after
JDK-8167372 to transition from native.

This only reproduces on older SPARC machines (I've hit it on a SPARC64 VII+) and therefore didn't
show up in our regular testing. I've verified the fix on this machine.

Thanks,
Tobias
