https://bugs.openjdk.java.net/browse/JDK-8038633

This is a bug tail of 8037226 changes.

Windows need an exception wrapper around getPsrInfo_stub() call in order 
to properly handle SEGV for YMM registers test.
The fix is based on code we already have in jni.cpp for 
test_error_handler().

Tested on machines which show the problem.

It will be backported into jdk8u20 which also have 8037226 changes.

Thanks,
Vladimir
