[Bug fortran/19310] unnecessary error for overflowing results

Steve,

I was just about to post an RFC to the list because this PR is requesting a
change of philosophy regarding compile time vs runtime behavior.  Your comment
about -fallow-inf-nan answers my question.  I can see where some users would
want the compile time error, while others may want to use, for example,
exp(1000) to give an infinity.

I think the patch will be straight forward including updating the appropriate
texi.  The -fallow-inf-nan can be applied to range_check in simplify.c and that
will cover most if not all relevant intrinsics.

The default behavior will be to do as is now and give the compile error.
