Is it something that would be relatively easy to change with a local 
patch for LLVM without introducing a lot of modifications? (only 
disabling GetElementPtrConstantExprs inlining)

This is really something that would help having simpler static analysis, 
even if additional analysis of the code can be used as a (quite ugly) 
workaround.

Thank you very much,
