Add SkSL unit test for unbraced blocks that optimize away. In most cases, this works properly and a `;` is emitted, but in one particular case (int x, y;) we get nothing.

Support half4 return values from main() in the SPIR-V code generator. This creates a helper function, _entrypoint, which invokes main() and assigns its result into sk_FragColor. We also make sure to prevent sk_FragColor from being dead-stripped from the code during IR generation. At present this is useful for allowing our SkSL test shaders to compile.

Remove usage of sqrt() as an optimization barrier in tests. In the majority of cases, a uniform is an equally good substitute, and replacing `sqrt(N)` with `unknownInput` actually makes the test clearer.

Update various shared/ tests to run in dm. These tests have updated to return green on success, or red on failure. Some tests were modified slightly to conform to ES2 limitations, or split into separate ES2 and ES3 parts.
