apply patches from http://www.es.ele.tue.nl/~rjordans/llvm-cbe-patches/ as of 20feb2013
include the CBackend files for real (ommitted before)
add Roel's 12mar2013 test/CodeGen/CBackend patch, which includes 3 tests (the array_of_array.ll currently fails, which is great because it is the exact feature desired--go test-driven development\!)
array_of_array test works
add 3-d array test
add test that function names come through
add simple (failing) test of printf working in the output C code; in printf_prints.c
revert to using structs wrappers for arrays, since otherwise the most basic of printf tests fails
Manual merge glycerine/cbe_revival.  Add both CBackend and JsBackend to makes.
