C reimplementation with intermediate printouts

At the WebKit meeting, Filip Pizlo required additional data to back my precision claims regarding 1ULP roundoff errors. I will provide the test program and the intermediate output values, for comparison.
The final result obtained by the C reimplementation on Linux/x64 and QNX/ARM is exactly the same as what is given by JavaScriptCore executing 3d-morph.js on these respective platforms.
