RFR: 8358756: [s390x] Test StartupOutput.java crash due to CodeCache size [v2]

[Amit Kumar]

> There isn't enough initial cache present which can let the interpreter mode run freely. So before even we reach to the compiler phase and try to bail out, in case there isn't enough space left for the stub compilation, JVM crashes. Idea is to increase the Initial  cache size and make it enough to run interpreter mode at least.
