This brings back the basics from SkSLFPTest.cpp. This file was removed entirely in http://review.skia.org/319029 but, in retrospect, it's still a good idea for dm to verify that CPPCodeGen and HCodeGen can do their jobs. And, like SkSLGLSLTestbed, this gives us a good place to attach the debugger in dm for testing CPP/H-specific code generation bugs.
