+1 on this, otherwise LGTM. Thanks for implementing this!



================
Comment at: llvm/include/llvm/IR/GlobalValue.h:426
   /// Return true if this global's definition can be substituted with an
   /// *arbitrary* definition at link time.  We cannot do any IPO or inlinining

----------------
Minor nit: We have extended this to now determine if a definition can be substituted with an arbitrary definition at link time or load time. 

I would suggest changing the first `link time` to `link time or load time`, and changing
`since the callee can be replaced with something arbitrary at link time.` to 
`since the callee can be replaced with something arbitrary.`,
