<p>r327219 added a new wrapper function called <b>llvm::sort</b>.
If EXPENSIVE_CHECKS is enabled, llvm::sort will randomly shuffle
the container before invoking std::sort. This will help uncover
non-deterministic ordering of objects having the same key.</p>
<p>All occurrences of std::sort have been changed to llvm::sort in
llvm/clang/polly repos.</p>
<p>Going forward please make sure to avoid use of std::sort and
instead use llvm::sort. Maybe we should add a note on the usage of
llvm::sort to the LLVM Coding Standards?<br>
