Yikes, this bug description is hard to read. I must have been in too deep when
writing it,
As far as I understand it, my problem was that the pointer value for "qux" was
available, but we couldn't find the right SDNode when building a SelectionDAG
because it was on the other side of a needless BitCast. And for various reasons
at the time, SelectionDAG wouldn't create DBG_VALUEs for arbitary VRegs
Some time later this [0] landed, which refers to this PR. I've just given the
"reproducer" a few runs and couldn't make it drop "qux", so I think it's fair
to say it's fixed. Thanks for prodding!
