i965/fs: Explicitly set the exec_size on the add(32) in interpolation setup
Soon we will start using the builder to explicitly set all the execution sizes. We could make a 32-wide builder, but the builder asserts that we never grow it which is usually a reasonable assumption. Since this one instruction is a bit of an odd-ball, we just set the exec_size explicitly. v2: Explicitly new the fs_inst instead of using the builder and setting exec_size after the fact. v3: Set force_writemask_all with the builder instead of directly. The builder over-writes it if we set it manually. Also, if we don't have force_writemask_all in the builder it will assert-fail on SIMD32.
