-; Lifetime intrinsics are typically just referencing a single alloca, but
-; sometimes PRE decides to totally optimize a redundant bitcast and insert
-; phis. We need to look through the phis. In the code below, l_1565.i has
-; an overlapping lifetime with l_766.i which is only visible if we can
-; see through phis.
