DFG_JIT implementation for sh4 architecture

I've tested this patch on my sh4 board using r153999 and I didn't see regressions when running
- Tools/Scripts/run-javascriptcore-tests
- Tools/Scripts/run-fast-jsc
- SunSpider 1.0
- v8-v4 test suite


v8-v4 test suite results on r153999 without this patch:
