nir: Destination component count of shader_clock intrinsic is 2
This fixes the following error when using ARB_shader_clock on i965:
vec1 32 ssa_0 = intrinsic shader_clock () () ()
intrinsic store_var (ssa_0) (clock_retval) (3) /* wrmask=xy */
error: src->ssa->num_components == num_components (nir/nir_validate.c:204)
