Log message:
	* basic-block.h (inside_basic_block_p, control_flow_insn_p): Declare.
	* cfgbuild.c (inside_basic_block_p, control_flow_insn_p): Make global.
	* invoke.texi (-fschedule-traces, -fschedule-superblocks): Document
	* flags.h (flag_superblock_scheduling, flag_trace_scheduling): Declare.
	* haifa-sched.c (unlink_other_notes): Unlink basic block notes.
	* params.def (tracer-min-branch-probability-feedback): Fix default value.
	* schedule-ebbs.c (params.h, profile.h): Include.
	(schedule_ebb): Return last basic block in the sequence.
	(fix_basic_block_boundaries, add_missing_blocks): New static functions.
	(schedule_ebbs): Use TRACER_MIN_BRANCH_PROBABILITY to discover traces;
	Use CFG for profile information.
	* flags.c (flag_superblock_scheduling, flag_trace_scheduling): New global
	variables.
	(lang_independent_options): Add -fschedule-superblocks, -fschedule-traces.
	(rest_of_compilation): Suppress crossjumping when trace scheduling is on;
	invoke superblock scheduling when asked for.
	(parse_options_and_default_flags):  Default to superblock scheduling for -O2
	and trace scheduling for -O3.
	(process_options): Imply tracer and superblock scheduling by trace scheduling.
	Imply 2nd scheduler pass by superblock scheduling.
	
	* params.def (tracer-min-branch-probability-feedback): Fix default.
	
	* final.c (compute_alignments): Use profile to avoid code bloat.
