John Stiles 16cbfb41df Implement statements and expressions in DSL C++ code generator.
This CL removes the bulk of the existing C++ code generator, especially
all the complex format-string assembly code. It has been replaced with
actual DSL code generation. Simple IR can now be successfully translated
to a working DSL fragment processor.

This CL also adds a simple test harness which is patterned after the
existing SkSLTest; it renders a pixel, reads it back, and fails the test
if the result isn't solid green (RGBA=0101).

This CL doesn't implement every feature. Some obvious gaps include:
- Sampling from children
- Uniforms/inputs of any kind
- Function calls of any kind
