RFR: 8315576: compiler/codecache/CodeCacheFullCountTest.java fails after JDK-8314837 [v2]

[Yi-Fan Tsai]

> CodeCacheFullCountTest disables code cache flushing, loads classes, makes the code cache running out of space (the remaining is insufficient for another nmethod), and disables compilers.
> The test expects two scenarios: 1) the process continues and terminates normally or 2) the adapters cannot be allocated in `refClass` and VirtualMachineError has been thrown and printed.
> 
> When the test runs with option `-Xcomp`, `-esa`, and `-XX:-TieredCompilation`, more codes are compiled and the code cache becomes full early. The adapters may not be allocated in `loadClass`, and VirtualMachineError has been thrown but wrapped in LambdaConversionException (`InnerClassLambdaMetafactory.buildCallSite`) and BootstrapMethodError (`BootstrapMethodInvoker.invoke`).
> VirtualMachineError may not be completely printed by `printStackTrace` in `ThreadGroup.uncaughtException` before the process terminated. This breaks the expected scenario 2.
> 
> The check of scenario 2 is removed from the test as it's not reliable.
> 
> The test has passed as below.
> 
> make test \
>     TEST="test/hotspot/jtreg/compiler/codecache/CodeCacheFullCountTest.java" \
>     JTREG="JAVA_OPTIONS=-Xcomp -ea -esa -XX:-TieredCompilation"
