cfgcleanup.c (cleanup_cfg): Detect cfglayout mode and set the CLEANUP_CFGLAYOUT flag when in cfglayout mode. 

* cfgcleanup.c (cleanup_cfg): Detect cfglayout mode and set
	the CLEANUP_CFGLAYOUT flag when in cfglayout mode.

	* Makefile.c (GTFILES): Add cfglayout.h.
	* gengtype.c (open_base_files): Likewise.
	* cfglayout.c (cfg_layout_function_footer,
	cfg_layout_function_header) Reindent to make gengtype happy.
	* cfglayout.h (cfg_layout_function_footer,
	cfg_layout_function_header): Add GTY(()) marker.

	* ifcvt.c (noce_try_sign_mask): Make sure INSN_B is non-null.
