gm107/ir: fix sign bit emission for FADD32I
When emitting OP_SUB, the sign bit for FADD and FADD32I is not at the same position. It's at position 45 for FADD but 51 for FADD32I. This fixes the following piglit test: tests/spec/arb_fragment_program/fdo30337b.shader_test Signed-off-by: Samuel Pitoiset <[email protected]> Reviewed-by: Ilia Mirkin <[email protected]> Cc: <[email protected]>
