Add Eclipse OMR to the big list of stuff

[rwy7]

Eclipse OMR is a C/C++ toolkit for building language runtimes. OMR has a high level JIT compilation library called JitBuilder, which is built on OMR's more general compilation framework. We also have a demo VM called Base9, and a small tutorial on adding a bytecode (and jitting that bytecode) here(pdf).

I'd be super happy if you could add our project to the list of C/C++ compilation frameworks.
