* basic-block.h (struct basic_block_def): Reorder fields to
eliminate interior padding. Remove 'partition' field.
(BB_DISABLE_SCHEDULE, BB_HOT_PARTITION, BB_COLD_PARTITION)
(BB_UNPARTITIONED, BB_PARTITION, BB_SET_PARTITION)
(BB_COPY_PARTITION): New macros.
* bb-reorder.c, cfgcleanup.c, cfglayout.c, cfgrtl.c, ifcvt.c
Replace all references to the 'partition' field of a basic
block with new macros.
* insn-notes.def: Delete NOTE_INSN_DISABLE_SCHED_OF_BLOCK.
* final.c (final_scan_insn): Don't handle it.
* modulo-sched.c: Set BB_DISABLE_SCHEDULE flag on g->bb
instead of emitting a NOTE_INSN_DISABLE_SCHED_OF_BLOCK note.
* sched-rgn.c (sched_is_disabled_for_current_region_p):
Look for a BB_DISABLE_SCHEDULE flag on the block instead of a note.
