[polly] Change std::sort to llvm::sort in response to r327219

Mandeep Singh Grang · Mandeep Singh Grang · commit daec0aa71f24 · 2018-03-13T05:25:23.000Z
Summary: r327219 added wrappers to std::sort which randomly shuffle the container before sorting. This will help in uncovering non-determinism caused due to undefined sorting order of objects having the same key. To make use of that infrastructure we need to invoke llvm::sort instead of std::sort.
