Hi,

I just pushed a fix for the following compiler related value type issues:
1) On Stack Replacement does not work if the OSR compiled code references a live value type in the interpreter state
2) There is a bug in the code that merges value types coming from multiple branches
3) C2 does not yet support static/final value type fields in objects

Static final value type field loads are now constant folded. I added tests for all these issues. 

Best regards,
Tobias
