tree.h (struct tree_common): Rename raises_flag to nothrow_flag.

        * tree.h (struct tree_common): Rename raises_flag to nothrow_flag.
        (TREE_NOTHROW): Rename from TREE_RAISES.
        * toplev.c (rest_of_compilation): Set it.
        * print-tree.c (print_node): Adjust.
        * tree.c (stabilize_reference, build, build1): Don't set TREE_RAISES.
        (stabilize_reference_1, get_unwidened, get_narrower): Likewise.
        * calls.c (emit_call_1): Add 'nothrow' parm.  Add
        REG_EH_REGION note as appropriate.
        (libfunc_nothrow): New fn.
        (emit_library_call, emit_library_call_value): Use it.
        (expand_call): Check TREE_NOTHROW.

cp:
        * call.c (build_call): Set TREE_NOTHROW on the CALL_EXPR as
        appropriate.
        * decl.c (define_function): Set TREE_NOTHROW on the FUNCTION_DECL.
        * except.c (call_eh_info, alloc_eh_object, expand_throw): Set
        TREE_NOTHROW or TREE_THIS_VOLATILE on the function as appropriate.
        * rtti.c (build_runtime_decl, get_tinfo_decl, build_dynamic_cast_1,
        expand_si_desc, expand_class_desc, expand_ptr_desc, expand_attr_desc,
        expand_generic_desc): Likewise.
