functiion.h (struct function): Add x_whole_function_mode_p.

	* functiion.h (struct function): Add x_whole_function_mode_p.
	(retrofit_block): Declare.
	* function.c (retrofit_block): New function.
	(identify_blocks): Add assertions.  Allow an incomplete set of
	block notes if we're still generating code for the function.
	* integrate.c: Include loop.h.
	(expand_inline_function): Call find_loop_tree_blocks to map block
	notes to blocks when in whole-function mode.  Use retrofit_block
	to insert new BLOCKs for the inlined function, rather than
	insert_block.
	* stmt.c (expand_fixup): Likewise.  Don't use pushlevel/polevel.
	* Makefile.in (integrate.o): Depend on loop.h.
