This fixes the logic that was causing ASAN to crash with #30289.

[semantic-arc-opts] Eliminate unneeded use of bisection that caused A…
7323ea9 
…SAN to fire.

I was being too clever here and in the process of "foot-gunned"
myself. Specifically, I was hoping to use bisection to do some is contained in
list tests. But the list that I actually bisected upon was not the original list
and was just based on the original sorted list! So the pointer comparison for
the bisect no longer worked. Since the bisection was on pointer addresses, if we
were lucky and the new addresses in the new array were sorted the same as the
original array, we wouldn't hit anything.

Going to do the ASAN test once we figure out why the ASAN bot is failing.

ASAN failure was this:

00:01:03 ******************** TEST 'Swift(macosx-x86_64) :: Syntax/round_trip_stdlib.swift' FAILED ********************

I don't think that is me.
