tree.h (boolean_type_node): Move from C/C++/Java frontends.
* tree.h (boolean_type_node): Move from C/C++/Java frontends.
(boolean_true_node, boolean_false_node): Likewise.
(enum tree_index): Add TI_BOOLEAN_{TYPE,FALSE,TRUE}.
* tree.c (build_common_tree_nodes): Init boolean_type_node.
(build_common_tree_nodes_2): Init boolean_{true,false}_node.
* stor-layout.c (set_sizetype): Handle an early BOOLEAN_TYPE.
* c-common.h (truthvalue_type_node): Renamed from boolean_type_node.
(truthvalue_true_node): Renamed from boolean_true_node.
(truthvalue_false_node): Renamed from boolean_false_node.
* c-decl.c: Just set truthvalue_* to integer_*.
* c-*.[ch]: s/boolean/truthvalue/. s/c_bool/boolean/.
* cp/decl.c: Just set truthvalue_* to boolean_*.
* java/java-tree.h: Move boolean_type_node et al to the back end.
