John Stiles 4d6310ab20 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.
