RFC: inbounds on getelementptr indices for global splitting
...or example by deriving a
pointer to one past the end of a partition (which may cause it to point to
another global).

represent references to partitions. However this is not enough at least for
vtables because other globals (e.g. VTTs) may need to contain pointers to
vtables.

[1] Specifically, if either of the whole-program devirtualization or
control flow integrity features are being used. In the former case, under
virtual constant propagation we are able to place propagated constants
directly in front of vi...
