[LLVMdev] Experimental fixes to CBackend

[Dmitry N. Mikushin]

Hi,

Please see the collection of test cases attached. To build everything
execute make in the top directory. Files with logs show how
compilation fails/succeeds, depending on patched/unpatched version of
llvm.

Could we setup this test suite as a regular test for C backend?

Thanks,
- D.
