Makefile.in (optabs.o): Add dependencies on basic-block.h and hard-reg-set.h. 

* Makefile.in (optabs.o): Add dependencies on basic-block.h and
	hard-reg-set.h.
	* basic-block.h (control_flow_insn_p): Fuction was exported.
	* cfgbuild.c (control_flow_insn_p): Fuction was made non-static.
	* optabs.c (emit_libcall_block): Emit REG_LIBCALL and REG_RETVAL
	notes only when the region is contained in a single basic block.
