RFR: 8325647: [IR framework] Only prints stdout if exitCode is 134 [v2]

[Marc Chevalier]

> On Linux, `assert` and such eventually use `abort` which give the return code 134 (128 + 6 (code of SIGABRT/SIGIOT)). On Windows, dying returns `-1` (exit code are more-or-less-signed int on Windows):

> So let's make the IR framework aware of this: we consider there was a JVM error if the OS is windows and the return code -1, or if it's 134 otherwise. I'm not sure what's the most idiomatic/robust way to check whether we are on Windows or not, but it's not customer code: it just needs to work for testing.
