RFR(XS) 8073990: Deprecated "UseVectoredExceptions" VM options still defined in several globals files

[Dmitry Dmitriev]

Hello,

Please review this small fix for JDK-8073990. Also, I need a sponsor for 
this fix, who can push it, because I'm not have a OpenJDK name.

This fix removes deprecated "UseVectoredExceptions" VM option from 
several header files related to aix_ppc and linux_ppc. Here a list of 
modified header files:
src/os_cpu/aix_ppc/vm/globals_aix_ppc.hpp
src/os_cpu/linux_ppc/vm/globals_linux_ppc.hpp

The "UseVectoredExceptions" VM option was deprecated by JDK-7188234 
<https://bugs.openjdk.java.net/browse/JDK-7188234>, but was leaved in 
several header files. Thus, I remove it from remaining header files in 
hotspot repo.

I am not build HotSpot with this fix.

Also, one moment about what I am not 100% sure is are copyrights. I 
update copyright for Oracle and SAP AG to 2015, but I am not sure that I 
shall update SAP AG copyright. Correct me if I am wrong and SAP AG 
copyright shall leaved unchanged. Thanks!
