Program Slice View

[oxinabox]

Often what I want when reading IR in Cthulhu is a program slice view.
Where I input/select a SSA statement,
and Cthulhu only shows me statemements that can effect that one. (or perhaps highlights them)
Which can in many cases be simply done by just tracing back all SSA statemements that appear on its right-hand-side and all of those etc etc).

This would be useful for hunting down type instabilities since often they are poisoned by one failure early that is just propagates onwards
