re PR fortran/81304 (Bogus warning with -Wsurprising and -fopenmp: Type specified for intrinsic function 'min' / 'max')

	PR fortran/81304
	* trans-openmp.c (gfc_trans_omp_array_reduction_or_udr): Set
	attr.implicit_type in intrinsic_sym to avoid undesirable warning.

	* testsuite/libgomp.fortran/pr81304.f90: New test.
