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.

Only include one variable per declaration statement This removes VarDeclarationsStatement entirely. VarDeclaration instances appear directly as statements in Programs. SkSL that declares multiple variables in a single declaration is transformed to represent that as a series of VarDeclaration statements. Similarly, global variable declarations are represented by GlobalVarDeclaration program elements, one per variable.

Eliminate inliner temporary variables for functions with a single exit. When we determine that a function only contains a single return statement, there is no need to create a temporary variable and store the result expression into a variable. Instead, we can directly replace the function-call expression with the return-statement's expression. This dramatically simplifies the final optimized output from chains of very simple inlined functions, which is a very common pattern for trees of Skia fragment processors.
