[8u] RFR 8160761: [TESTBUG] Several compiler tests fail with product bits

[Aleksey Shipilev]

Original fix:
   https://bugs.openjdk.java.net/browse/JDK-8160761
   https://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/e6cf2e3fba31

This is the testfix follow after JDK-8156803. Only DekkerTest hunk applies, because all other tests 
are missing from 8u. Then DekkerTest hunks does not apply cleanly, because compiler test package 
declarations are not yet in 8u. There are no more mentions of either StressLCM or StressGCM anywhere 
else.

8u RFR:
   https://cr.openjdk.java.net/~shade/8160761/webrev.8u.01/

Testing: affected test on Linux x86_64 {fastdebug,release}; grepping {StressLCM,StressGCM}
