[9] RFR(S): 8060196: CodeHeap for 'non-nmethods' is full

[Tobias Hartmann]

Hi,

please review the following patch.

Bug: https://bugs.openjdk.java.net/browse/JDK-8060196
Webrev: http://cr.openjdk.java.net/~thartmann/8060196/webrev.00/

Problem:
CodeCache::is_full() returns true if the non-nmethod code heap is full but we 
can still store non-nmethod code in the non-profiled code heap and therefore 
should not disable compilation (see comment 'fallback solution' in 
CodeCache::allocate).

Solution:
Adapt CodeCache::is_full() to not check the non-nmethod code heap. I also fixed 
the CodeHeap is full warning to suggest increasing the non-profiled code heap.

Thanks,
Tobias
