log:
BB [7, 8): begin {}, end {}, livein {}, liveout {}
BB [1, 2): begin {}, end {}, livein {}, liveout {}
...
But it is not convenient to know what the basic block is.
So I add the basic block name to it.

If we can't identify alloca used in lifetime marker we
need to assume to worst case scenario.

Code does not track terminators and do not expose them through interface.
State there is just a state of the last instruction or entry.
So this information is just redundant and doesn't need to be tested.
Summary:
Extend StackLifetime with option to calculate liveliness
where alloca is only considered alive on basic block entry
if all non-dead predecessors had it alive at terminators.
Depends on D82043.
