Fix an obscure bug in PointerUnion that would bite PointerUnion3/4. Basically,
...
when checking isNull(), we'd pick off the sentinel bit for the outer
PointerUnion, but would not recursively convert the inner pointerunion to bool,
so if *its* sentinel bit is set, isNull() would incorrectly return false.
No testcase, because someone hit this when they were trying to refactor code
to use PointerUnion3, but they since found a better solution.

Allow loop unrolling to get known trip counts from ScalarEvolution.

SCEV unrolling can unroll loops with arbitrary induction variables. It
is a prerequisite for -disable-iv-rewrite performance. It is also
easily handles loops of arbitrary structure including multiple exits
and is generally more robust.
This is under a temporary option to avoid affecting default
behavior for the next couple of weeks. It is needed so that I can
checkin unit tests for updateUnloop.
