Before JDK-[8293503](https://bugs.openjdk.org/browse/JDK-8293503), this file has prefixed PR: `8290023: Remove use of IgnoreUnrecognizedVMOptions in gc tests`, it remove jvm option `-XX:+IgnoreUnrecognizedVMOptions`, and split all the test config to 32 bit and 64 bit, because 32bit jvm doesn't support option `-XX:-UseCompressedClassPointers`. Maybe I should backport this patch before backport of JDK-[8293503](https://bugs.openjdk.org/browse/JDK-8293503), or ignore this patch? I think this patch is useful.
> 2. The original JDK-[8293503](https://bugs.openjdk.org/browse/JDK-8293503) delete `gc/metaspace/TestMetaspacePerfCounters.java#Epsilon-64 8293503 generic-all` in `test/hotspot/jtreg/ProblemList.txt`. It's not needed to to in jdk17u-dev.

I creat a new [PR](https://github.com/openjdk/jdk17u-dev/pull/2438) for the prefixed backport [JDK-8290023](https://bugs.openjdk.org/browse/JDK-8290023)
