[Mesa-dev] [PATCH] i965/vec4/nir: Emit single MOV to generate a scalar constant.

If an immediate is written to multiple channels, we can load it in a single writemasked MOV. total instructions in shared programs: 6285144 -> 6261991 (-0.37%) instructions in affected programs: 718991 -> 695838 (-3.22%) helped:5762 --- The shader-db numbers are
