	* function.h (enum function_frequency): Move declaration
	out of struct function.
	(struct function): Move bool fields and the enum to the bitfield
	section.  Reorder elements to avoid padding.  Remove unused
	fields left over from the RTL inliner removal.
	* function.c (free_after_compilation): Do not zero removed fields.
	* Makefile.in (ipa-reference.o): Add $(FUNCTION_H) dependency.
	(ipa-type-escape.o): Likewise.
