[ARM] Recognize t2LoopEnd for software pipelining
- Add t2LoopEnd to TargetInstrInfo::analyzeBranch and
related functions. As there are many side effects of
analyzing a branch, only do so if software pipelining
is enabled to maintain previous behavior when pipelining
is not desired.
- Make sure that t2LoopEndDec is immediately followed by
a t2B when it is synthesized from a t2LoopEnd. This is
done because the t2LoopEnd might have acquired a
fall-through path, but IfConversion assumes that
fall-through are only possible on analyzable branches.
