* Makefile.in (cfgexpand.o): Depend on $(INSN_ATTR_H).
* genattrtab.c (check_tune_attr, find_tune_attr): New functions.
(make_automaton_attrs): If find_tune_attr returns non-NULL,
write separate internal_dfa_insn_code_* and insn_default_latency_*
functions for each attribute's value and emit init_sched_attrs
function and function pointers.
* genattr.c (const_attrs, reservations): New variables.
(gen_attr): Add const attributes to const_attrs vector.
(check_tune_attr, find_tune_attr): New functions.
(main): Add reservations to reservations vector. If find_tune_attr
returns true, add prototype for init_sched_attrs and make
internal_dfa_insn_code and insn_default_latency function pointers,
otherwise define init_sched_attrs as dummy macro.
* cfgexpand.c: Include insn-attr.h.
(gimple_expand_cfg): Call init_sched_attrs.
