RFR(XS): 8232005: [s390] More exception checks missing in interpreter

[Doerr, Martin]

Hi,

the template interpreter on s390 misses more exception checks when calling VM functions which may install an async exception (like java.lang.ThreadDeath) at a safepoint.

Bug:
https://bugs.openjdk.java.net/browse/JDK-8232005

These are the two places I found:

Please review.

Best regards,
Martin
