[patch] committed: minor sched-int.h and sched-deps.c fixes


In sched-deps.c:deps_analyze_insn there's no need to look for
EH_REGION notes, they don't exist until just before final. This
assert, and some code in alpha.c (PR56858), are the only remaining
meaningful references outside final.c

In sched-int.h, the header is only non-empty if INSN_SCHEDULING is
defined. After "#ifdef INSN_SCHEDULING" the first header included is
insn-attr.h - which defines (or not) INSN_SCHEDULING. So move that
include outside the "#ifdef INSN_SCHEDULING" guard.

Bootstrapped and tested on several targets over the past three weeks. Committed.


        * sched-deps.c (deps_analyze_insn): Do not check for EH_REGION insn
        notes, they are emitted only just before final.
        * sched-int.h: Include insn-attr.h before checking INSN_SCHEDULING.
