This revision is now accepted and ready to land.

I just did a quick check against `llvm/test/Instrumentation/AddressSanitizer/adaptive_global_redzones.ll`, compiling and linking it as a DSO, and it looks right (only the sizes change).

One thing to bear in mind is that some sanitizers (like HWASan) also change the alignment of the global variables as well as the size, so sanitizers will always be an ABI break, but I agree this patch makes things less confusing rather than more confusing.
