	* ipa-inline-transform.c (clone_inlined_nodes): Use min of edge count
	and callee count to get clone count.
	* tree-inline.c (expand_call_inline): Use callee count instead of bb
	count in copy_body.
	* tree-cfg.c (gimple_merge_blocks): Updates bb count with max count.
	* ira-int.h (REG_FREQ_FROM_EDGE_FREQ): Use optimize_function_for_size_p.
	* regs.h (REG_FREQ_FROM_BB): Likewise.
	* cfghooks.c (make_forwarder_block): Use direct computation to
	get fall-through edge's count and frequency.
