        * check.c (gfc_check_bessel_n2): New function.
        * gfortran.h (gfc_isym_id): Add GFC_ISYM_JN2 and GFC_ISYM_YN2.
        * intrinsic.c (add_functions): Add transformational version
        of the Bessel_jn/yn intrinsics.
        * intrinsic.h (gfc_check_bessel_n2,gfc_simplify_bessel_jn2,
        gfc_simplify_bessel_yn2): New prototypes.
        * intrinsic.texi (Bessel_jn, Bessel_yn): Document
        transformational variant.
        * simplify.c (gfc_simplify_bessel_jn, gfc_simplify_bessel_yn):
        Check for negative order.
        (gfc_simplify_bessel_n2,gfc_simplify_bessel_jn2,
        gfc_simplify_bessel_yn2): New functions.
