Create golden outputs for SkSL blend functions. Several blend functions generate a surprisingly large amount of code, and appear to have opportunities for further optimization. At any rate, if we make compiler changes that would affect the output of a blend function, I think we would want to see the changes reflected in our golden outputs.

Add golden outputs for the Metal backend. This CL also updates the blend tests to use sk_FragColor instead of returning a half4, as the Metal backend assumes that a fragment processor's `main` will return void and always synthesizes a `return *_out;` at the end.

Revert "Inline functions of the form 'return (expr)' only." This reverts commit 92748af1a5051e9fe329c8200f0fa3b47aadbdd7. Reason for revert: SkSLCommaSideEffects_GPU crashing on Android Original change's description: > Inline functions of the form 'return (expr)' only. > > This drastically reduces the number of functions which we allow to be > inlined. If this change does not hurt our performance, it will allow us > to trivially remove hundreds of LOC.
