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.

Avoid creating unnecessary scopes during inlining. The additional scopes were harmless, but didn't really add any value. Originally they were used to tightly scope inlined variables, but we now mangle inlined variable names.
