RFR (s) : 8145740: Visual Studio pragmas should be guarded by #ifdef _MSC_VER

[Baesken, Matthias]

Hello,
   can you please review and sponsor this change :

https://bugs.openjdk.java.net/browse/JDK-8145740
http://cr.openjdk.java.net/~clanger/webrevs/8145740.0/

Some details :

     while  Visual Studio pragmas in shared code are usually guarded with  _MSC_VER in the hotspot codebase
( see for example   taskqueue.hpp or  compressedStream.cpp ) , the guarding is missing in   src/share/vm/utilities/growableArray.hpp  ,
which is not really a "good thing"  for other compilers .


Thanks and regards, Matthias
