    spirv: Only split blocks
    Instead of splitting every per-vertex struct, just split the ones that
    are actually blocks.  The reason for the split is so that we have
    separate variables for separate locations, qualifiers, and builtin
    decorations.  The vulkan spec only allows these on members of blocks.

Yep, I can confirm it renders OK with radv 18.3.2 / llvm 7.0.1, but font is broken with radv in Mesa master / llvm 9.0
