ac: fix nir_op_f2f64
Without this we get the error "FPExt only operates on FP" when
converting the following:
vec1 32 ssa_5 = b2f ssa_4
vec1 64 ssa_6 = f2f64 ssa_5
Which results in:
%44 = and i32 %43, 1065353216
%45 = fpext i32 %44 to double
With this patch we now get:
%44 = and i32 %43, 1065353216
%45 = bitcast i32 %44 to float
%46 = fpext float %45 to double
