This reverts commit 23d8f94535.
Reason for revert: SkSL_ArrayComparison test causes Adreno 630/640 to crash in Vulkan
Original change's description:
> Fix array-of-matrix/struct comparisons in Metal.
>
> Metal needs helper functions in order to compare arrays, structs, and
> matrices. Depending on the input code, it was possible for the
> array-comparison helper to be emitted before a matrix-comparison
> or struct-comparison helper. If this occurred, array comparisons of that
> matrix or struct type would fail, because the operator== for the array's
> inner type was defined after array==, and Metal (like C++) parses
> top-to-bottom and only considers functions declared above the current
> function.
>
> We now emit prototypes for all the array, struct and matrix helper
> function. These prototypes are emitted above any helper functions. This
> ensures visibility no matter how your comparisons are organized.
