target-arm: Make Neon helper routines use correct FP status

Make the Neon helper routines use the correct FP status from the CPUEnv rather than using a dummy static one. This means they will correctly handle denormals and NaNs and will set FPSCR exception bits properly. Signed-off-by: Peter Maydell <[email protected]> Signed-off-by: Aurelien Jarno <[email protected]>
