This seems to have broken MultiSource/Applications/JM/ldecod.

I now see the following assert:

bool polly::Scop::buildAliasGroups(llvm::AliasAnalysis&): Assertion 
`AG.size() > 1 && "Alias groups should contain at least two accesses"' 
failed.
0  clang           0x00000000028dfc62 
llvm::sys::PrintStackTrace(_IO_FILE*) + 34
1  clang           0x00000000028df6d3
