independent of the front-end.

* builtin-attrs.def: Define new attribute lists for use in
builtins.def.
* builtins.def [DEF_BUILTIN]: Modify to take an additional
ATTRS argument, an enumerated value defined in builtin-attrs.def
that represents the attribute list for the builtins. Modify
all builtin functions to pass an appropriate attribute list.
Specify "abort", "exit", "_exit" and "_Exit" builtins here with
their required noreturn attributes.
* tree.h (enum_builtin_function): Ignore the additional parameter
to DEF_BUILTIN.
* builtins.c (built_in_names): Likewise.
* c-common.c: (builtin_function_2): Replace the "int noreturn_p"
argument with a tree representing the functions attribute list.
Pass this "attrs" argument to builtin_function. No longer handle
the noreturn_p processing manually.
(built_in_attributes): Move the definitions from builtin-attrs.def
before c_common_nodes_and_builtins.
(c_common_nodes_and_builtins): Handle the new ATTRS parameter in
DEF_BUILTIN, passing it to both builtin_function and the changed
builtin_function_2.
* doc/extend.texi: Document __builtin_abort, __builtin_exit,
__builtin__exit and __builtin__Exit.
* java/builtins.c (initialize_builtins): Ignore the additional
parameter to DEF_BUILTIN. Handle more C/C++ specific junk in
the builtins.def file.
