i915: fix vertex atan regression

This is a regression happening with the commit 87b99d5797 ("nir: use copysign for atan").
Indeed, the opcode "copysign" was generating an incompatible i915 sequence.

For instance, this issue is triggered with
"deqp-gles2 --deqp-case=dEQP-GLES2.functional.shaders.operator.angle_and_trigonometry.atan2.highp_float_vertex":
deqp-gles2: ../src/compiler/nir/nir_lower_int_to_float.c:239: lower_alu_instr: Assertion `nir_alu_type_get_base_type(info->output_type) != nir_type_int && nir_alu_type_get_base_type(info->output_type) != nir_type_uint' failed.

Fixes: c4cec84231 ("nir/i915g/r300/nv30: skip marking varyings as flat in some drivers")
