Change std::sort to llvm::sort to detect non-determinism.

LLVM added wrappers to std::sort (r327219) that randomly shuffle the
container before sorting. The goal is to uncover non-determinism due to
undefined sorting order of objects having the same key.

This can be enabled with -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON.
