Feeding isSafeToSpeculativelyExecute its DataLayout pointer (in Sink)
Feeding isSafeToSpeculativelyExecute its DataLayout pointer (in Sink)

This is the one remaining place I see where passing
isSafeToSpeculativelyExecute a DataLayout pointer might matter (at least for
loads) -- I think I got the others in r212720. Most of the other remaining
callers of isSafeToSpeculativelyExecute only use it for call sites (or
otherwise exclude loads).
