RFR: 7012961 runtime/jni/WindowsExceptionFilter/WindowsExceptionFilter01 crashes on windows-amd64

[Zhengyu Gu]

This is another nightly clean up bug, and it is targeted to JDK9.

The comment on original code line 2280 - 2281 is not accurate, since 
compiled code and intrinsic routines also can cause EXCEPTION_FLT_*. 
This particular testcase actually triggers EXCEPTION_FLT_DIVIDE_BY_ZERO 
from intrinsic routine.
