Sorry about that. Anything serious?

This make LTO happy but causes several regressions on the tests for
(MIN|MAX)(VAL|LOC).

I have looked at the failures for gfortran.dg/scalar_mask_2.f90 and I think
they come from

<     _gfortran_smaxloc0_4_r4 (&atmp.30, D.3514, 0B, D.3516);

>     _gfortran_smaxloc0_4_r4 (&atmp.30, D.3511, &C.3512);

'<' with the patch '>' without it.
