location" idea is true of SelectionDAG, but it might fall apart with other
optimisations.

I don't believe there's any relationship between DBG_VALUE locations and !dbg
source locations right now. This is actually one of my pet peeves, that
variable locations and the line program don't necessarily line up into
something c...

[RFC] A value-tracking LiveDebugValues implementation

tl;dr: Let's please consider using a new implementation of LiveDebugValues
that produces richer information, might be slightly faster, but mostly will
support the instruction referencing and value tracking paradigm from my RFC [0]
rather than the location tracking that LiveDebugValues does today.
In that RFC, the main motivator is to treat variable locations a bit more
