Ben Clayton	4135ea55eb	writer/hlsl: Don't wrap arrays in structures ... FXC has trouble dealing with these. This was originally added to handle returning arrays as structures. HLSL supports typedefs, which is a much simpiler solution, and doesn't upset FXC.

Ben Clayton	2bb45389b7	writer/hlsl: Zero initialize with (T) 0 ... For structures and arrays. This behaves identically to the per-element zero-initialization, but can be significantly less verbose.

Ben Clayton	0597a2b51b	Add transform/WrapArraysInStructs ... And replace the MSL writer's logic to do this with the transform. We need to do the same thing in HLSL, and in the future GLSL too.

Ben Clayton	5d2f34ecf2	writer/hlsl: Simplify emission logic, clean up output ... And fix issues where global variables would not be emitted unless they were transitively referenced by an entry point. This change requires crbug.com/tint/697 to be fixed before landing.
