gen7/cmd_buffer: SCISSOR_RECT structs are tightly packed
The pointer has to be 32-byte aligned, but the structs themselves are 2
dwords each, tightly packed.

HACK/i965/surface_formats: Mark A4B4G4R4 as being supported
The table has this marked as unsupported on all gens, but I don't really
believe that given how early it is in the table. I've tested and it seems
to work on Broadwell. The Bspec says that it sould be renderable on SKL+
but alpha blending is questionable.
Side note: We really need to audit the format table again.

anv: Support swizzled formats.
Some formats require a swizzle in order to map them to actual hardware
formats. This allows us to turn on two new Vulkan formats.
