PR fortran/97272 - Wrong answer from MAXLOC with character arg

The optional KIND argument to the MINLOC/MAXLOC intrinsic must not be
passed to the library function, as the kind conversion of the result
is treated explicitly elsewhere.

gcc/fortran/ChangeLog:

	PR fortran/97272
	* trans-intrinsic.c (strip_kind_from_actual): Helper function for
	removal of KIND argument.
	(gfc_conv_intrinsic_minmaxloc): Ignore KIND argument here, as it
	is treated elsewhere.

gcc/testsuite/ChangeLog:

	PR fortran/97272
	* gfortran.dg/pr97272.f90: New test.
