[12] Closed RFR(XS) 8208550: [TESTBUG] vmTestbase_vm_* tests executed twice in Tier2, Tier3

[Vladimir Kozlov]

https://bugs.openjdk.java.net/browse/JDK-8208550

vmTestbaseCompiler is included twice: in tier2CompilerTests and in jtregCompiler. Remove it from 
tier2CompilerTests which is always used when jtregCompiler is also used (tier2 and tier3).
