RFR(S): 8035396: Introduce accessor for tmp_oop in frame.

[Vladimir Kozlov]

Hi, Goetz

Why you did not add it to src/cpu/ppc/vm/frame_ppc.inline.hpp?
I know that ppc use C++ Interpreter in our sources but you will need it 
anyway later.

The code in frame.inline.hpp should be also guarded with !PPC32:

#if defined(CC_INTERP) && !defined(PPC32)

Changes look reasonable. I did closed changes and it is working. I am 
testing it in JPRT now.

Thanks,
Vladimir
