Contribution to the wiki page "C2 Compilation Phases"

[Marcelino Rodriguez cancio]

Hi, 

I could not avoid noticing that the C2 Compilation Phases page of the OpenJDK wiki is empty: https://wiki.openjdk.java.net/display/HotSpot/C2+compilation+phases 

I was requested to write down that information for my team and I would like to contribute the resulting document to the community. Please find my report here: 

http://marcelinorc.com/2016/05/11/phases-of-the-java-hostpot-c2s-compiler/ 

The report talks about the phase ordering of the C2 compiler, making emphasis on the optimizations applied during the compilation process and providing links to the C++ implementation in the Hostpot’s repository. 

The information there is summarized from other sources, as well as by reading the C2's code. So if someone could review it and provide some feedback it would be awesome. 

Best 
Marcelino
