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

[Vladimir Kozlov]

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
