RFR: 8157954: [TESTBUG] G1 tests fail with defined MaxGCPauseMillis

[Michail Chernov]

Hi Jon,

We going to perform execution of G1 specific tests with non-standard 
pauses. Typical log looks like:

MaxGCPauseMillis (1000) must be less than GCPauseIntervalMillis (50)
GCPauseIntervalMillis (50) must be greater than MaxGCPauseMillis (1000)
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

All tests explicitly set MaxGCPauseMillis to some value, so if we pass 
next option to VM ( -XX:MaxGCPauseMillis=30 
-XX:GCPauseIntervalMillis=50) tests fail and VM gets the VM options 
conflict.

For example, test/gc/g1/ihop/TestIHOPErgo.java defines next options 
during testing - -XX:MaxGCPauseMillis=30000, so non-standard GC pauses 
causes to options range violation.

This change excludes execution of tests if MaxGCPauseMillis is defined.

Thanks
Michail
