This reverts commit 16cbfb41df.
Reason for revert: using ES3 features, breaks on ANGLE ES2 bots
Original change's description:
> 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
>
