--- Comment #3 from Tim Northover <t.p.northover at gmail.com> ---
Thanks for the test-case. I believe it's the fact that the VLDMIA_UPD is at the
beginning of the block that messes up the tracking rather than isCSRestore.

I actually think the entire idea of tracking FirstPop like that was misguided:
the folding *has* to happen precisely where we'd insert an sp-update to be
valid, which is the entire reason MBBI exists. We should just be using that.

This one should be fixed in r196493. I really hope it's the last.
