RFR(S): 8234605: C2 failed "assert(C->live_nodes() - live_at_begin <= 2 * _nodes_required) failed: Bad node estimate: actual = 208 >> request = 101"

[Patric Hedlin]

Dear all,

I would like to ask for help to review the following change/update:

Issue:  https://bugs.openjdk.java.net/browse/JDK-8234605
Webrev: http://cr.openjdk.java.net/~phedlin/tr8234605/


Turning assert into (universal) logging. This issue (now) manifest 
itself very seldom (typically on small estimates) and has thus served 
its purpose to help trim the node budget estimates to some reasonable 
level. Logging should be sufficient going forward.


Testing: tier1-2


Best regards,
Patric
