8253748: StressIGV tests fail with release VMs

[DamonFool]

The following StressIGV tests fails with release VMs

• compiler/arguments/TestStressIGVNOptions.java
• compiler/debug/TestGenerateStressSeed.java
• compiler/debug/TestStressIGVN.java

The reason is that VM option 'StressIGVN' is diagnostic and must be enabled via -XX:+UnlockDiagnosticVMOptions.

The fix adds '-XX:+UnlockDiagnosticVMOptions' option.
And compiler/debug/TestStressIGVN.java should be only available for debug VMs since it depends on -XX:+TraceIterativeGVN.
