Pointers, so we can get the necessary attributes without adding
a new symbol.
(attr_decl1): Added code to catch pointee symbols and "fix"
their array specs.

(gfc_mod_pointee_as): New method.
* expr.c (gfc_check_assign): added a check to catch vector-type
assignments to pointees with an unspecified final dimension.

gfc_match_option.flag_cray_pointer.
(gfc_handle_option): Deal with -fcray-pointer.
* parse.c:(resolve_equivalence): Added code prohibiting Cray
pointees in equivalence statements.
* resolve.c (resolve_array_ref): Added code to prevent bounds
checking for Cray Pointee arrays.
(resolve_equivalence): Prohibited pointees in equivalence
statements.
* symbol.c (check_conflict): Added Cray pointer/pointee
attribute checking.
(gfc_add_cray_pointer): New
(gfc_add_cray_pointee): New
(gfc_copy_attr): New code for Cray pointers and pointees
* trans-array.c (gfc_trans_auto_array_allocation): Added code to
prevent space from being allocated for pointees.
(gfc_conv_array_parameter): Added code to catch pointees and
correctly set their base address.
* trans-decl.c (gfc_finish_var_decl): Added code to prevent
pointee declarations from making it to the back end.
(gfc_create_module_variable): Same.
* trans-expr.c (gfc_conv_variable): added code to detect and
translate pointees.
(gfc_conv_cray_pointee): New.
* trans-intrinsic.c (gfc_conv_intrinsic_loc): New.
(gfc_conv_intrinsic_function): added entry point for loc
translation.
