Hi,

please review the following patch for bug 8029436.

*Problem:*
The JVM option CICompilerCount holds the number of compiler threads. If 
CICompilerCountPerCPU is enabled, the number of compiler threads is 
adjusted at runtime by the policies. The value CICompilerCount is not 
updated.
Bug: https://bugs.openjdk.java.net/browse/JDK-8029436

*Solution:*
CICompilerCount is updated in AdvancedThresholdPolicy::initialize, 
SimpleThresholdPolicy::initialize and NonTieredCompPolicy::initialize. A 
warning is printed if the user both sets CICompilerCount and 
CICompilerCountPerCPU.

*Tests:*
JPRT

Thanks,

Tobias
