RFR(M): 8059592: Recent bugfixes in ppc64 port.

[Lindenmaier, Goetz]

Hi Vladimir, 

I don't know exactly what happened, Martin fixed that.
We have test where we set very small code cache size to 
stress the code cache infrastructure, and that test failed.
Martin, can you give more detail?

Best regards,
  Goetz

Looks fine. One question is how you can have failing state during code 
generation?:

if (Compile::current()->env()->failing()) { return; } // Code cache may 
be full.

There should be bailout in opto/output.cpp when codecache is full.
Did it happen because estimated buffer size was less then needed?

Thanks,
Vladimir
