John Stiles 3934647d22 Reland "Implement operator== and != for Metal structs and arrays." 
This is a reland of 830c69ca66

Original change's description:
> Implement operator== and != for Metal structs and arrays.
>
> GLSL/SkSL assumes that == and != on struct/array types should work.
> We need to emit equality and inequality operators whenever we find code
> that compares a struct or array.
>
> Structs and arrays can be arbitrarily nested, and either type can
> contain a matrix. All of these things need custom equality operators in
> Metal. Therefore, we need to recursively generate comparison operators
> when any of these types are encountered.
>
> For arrays we get lucky, and we can cover all possible array types and
> sizes with a single templated operator== method. Structs and matrices
> have no such luck, and are generated separately on a per-type basis.
>
> For each of these types, operator== is implemented as an equality check
> on each field, and operator!= is implemented in terms of operator==.
> Equality and inequality are always emitted together. (Previously, matrix
> equality and inequality were emitted and implemented independently, but
> this is no longer the case.)
