The old one generates useless instructions in there, found while
comparing geometry shaders between RadeonSI and RADV.
This improves all Vulkan demos that use geometry shaders, +4%
for deferredshadows, +9% for viewportarray, +7% for
geometryshader on Polaris10.
This seems to also improve DOW3 a little bit (+1%).

This allows to reduce the number of dwords that are loaded
with buffer_load_format_xyzw. For example, when the only used
channel is 1, the driver will emit buffer_load_format_x instead.
