RFR: 8152637: Create a stack allocatable LogStream class

[Stefan Karlsson]

Hi all,

Please review this patch to create a stack allocatable LogStream class 
that embeds the ResourceMark.

http://cr.openjdk.java.net/~stefank/8152637/webrev.01
https://bugs.openjdk.java.net/browse/JDK-815263

The patch is applied on top of the patch in:
http://mail.openjdk.java.net/pipermail/hotspot-dev/2016-March/022303.html

I've converted the code in binaryTreeDictionary.cpp to show how to use 
the class.

Test: new internal vm test, jprt

Thanks,
StefanK
