John Stiles 80f240a3d3 Revive SkSLFPTestbed for basic verification of CPP/H codegen.
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.
