[8u] RFR (XS) 8255734: VM should ignore SIGXFSZ on ppc64, s390 too

[Aleksey Shipilev]

Original bug:
   https://bugs.openjdk.java.net/browse/JDK-8255734
   https://github.com/openjdk/jdk/commit/54c88132

The patch does not apply cleanly to 8u, because s390x port is not available in 8u, and there is 
enough context changes (mostly due to JDK-8252324) to fail the automatic patch. 8u variant:
