[Mesa-dev] [PATCH] i965: Use a ZERO() macro to initialize GENX_* structs.

[Rafael Antognolli]

gen4 have commands which start with KernelStartPointer, which is a
struct, so if we initialize it struct = { 0 }, we get warnings on some
compilers.

This macro works around that and will silent such warnings.
