* ira-int.h (ira_allocno): Rename left_conflicts_num to
left_conflicts_size.
(ALLOCNO_LEFT_CONFLICTS_NUM): Rename to
ALLOCNO_LEFT_CONFLICTS_SIZE.

remove_allocno_from_bucket_and_push,
allocno_spill_priority_compare, push_allocnos_to_stack,
setup_allocno_available_regs_num): Use ALLOCNO_LEFT_CONFLICTS_SIZE
instead of ALLOCNO_LEFT_CONFLICTS_NUM.
(setup_allocno_left_conflicts_num): Ditto.  Rename to
setup_allocno_left_conflicts_size.
(put_allocno_into_bucket): Use ALLOCNO_LEFT_CONFLICTS_SIZE
instead of ALLOCNO_LEFT_CONFLICTS_NUM and
setup_allocno_left_conflicts_size instead of
setup_allocno_left_conflicts_num.

* ira-build.c (ira_create_allocno): Use
ALLOCNO_LEFT_CONFLICTS_SIZE instead of
ALLOCNO_LEFT_CONFLICTS_NUM.
