Reloop llvm IR output, to have fors, ifs, whiles. From https://reviews.llvm.org/D12744
I'm using this personally for my cuda-on-cl project, to 'reloop' the OpenCL, so it's not full of gotos and labels :-)
This code came originally from From https://reviews.llvm.org/D12744 , ie WebAssembly target for llvm.
I * think* the WebAssembly reloop may have come originally from https://github.com/kripken/Relooper , but I'm unclear on this point at this time.
I havent definitively decided to use this coe or not in cuda-on-cl, but it sounds promising. Probably better than rolling my own...
