[LLVMdev] [RFC] Less memory and greater maintainability for debug info IR
...If we integrate a side-table of `MDLineTable`s into its uniquing,
the overhead is only ~12B / line table entry, or ~80MB. This saves
520MB.
This is somewhat perpendicular to redesigning the metadata format,
but IMO it's worth doing as soon as it's possible.
4. Create `GenericDebugMDNode`, a transitional subclass of `MDUser`
through an intermediate class `DebugMDNode` with an
allocation-time-optional `CallbackVH` available for referencing
non-metadata. Change `DIDescriptor` to wrap a `DebugMDNode` instead
of an `MDNode`.
This saves another ~960MB, for a runni...
