[Bug fortran/33197] Fortran 2008: math functions and other small changes

Tobias noted the following also need updating:

3999:      /* Fortran 2008 draft allows BIND(C) for internal procedures.  */
4000-      if (gfc_current_state () == COMP_CONTAINS
4001-     && sym->ns->proc_name->attr.flavor != FL_MODULE
4002-     && gfc_notify_std (GFC_STD_GNU, "Extension: BIND(C) attribute at %L "
4003-                        "may not be specified for an internal procedure",
--
4733:      /* The following is allowed in the Fortran 2008 draft.  */
4734-      if (gfc_current_state () == COMP_CONTAINS
4735-     && sym->ns->proc_name->attr.flavor != FL_MODULE
4736-     && gfc_notify_std (GFC_STD_GNU, "Extension: BIND(C) attribute at "
4737-                        "%L may not be specified for an internal
procedure",

ERF and ERFC should be simplified, it's easy since MPFR has these functions.

And, quoting my comment #6:
"Two more remarks on that: ASINH, ACOSH and ATANH need to accept COMPLEX
arguments. Some other functions also should be extended that way (ASIN, ACOS...
and probably many more).

Also, one very annoying feature: BESSEL_JN and BESSEL_YN have two forms, with 2
or 3 arguments. What's more, these two forms have very different properties
(the first one is elemental, the second one is transformational), and I don't
know how to implement that in the current handling of intrinsics!"
