llvm/llvm-project#91101 propagates range information across inlining,
resulting in more metadata in this test. Tolerate the range metadata if
it appears.
This test started failing on LLVM 18 after change
61118ffd04aa6d1f9ee92daae4deb28bd975d4ab. As far as I can tell, it's
just good fortune that LLVM is able to sniff out the new noalias here,
and it's correct.
