[patch, fortran] Fix PR 85896, type confusion with min and max

[Thomas Koenig]

Hello world,

the attached patchlet fixes a rejects-valid bug by simply ignoring the
type for max and min during simplification. This is correct
because setting the type of a generic intrinsic function has
no effect.

It is a rare pleasure to fix a bug by removing code only :-)

Regression-tested. OK for trunk?

Regards

Thomas
