Duncan P. N. Exon Smith c128f3b34c UseListOrder: Fix undefined behaviour 
This commit fixes undefined behaviour that caused the revert in r214249.

The problem was two unsequenced operations on a `DenseMap<>`, giving
different behaviour in GCC and Clang.  This:

    DenseMap<T*, unsigned> DM;
    for (auto &X : ...)
      DM[&X] = DM.size() + 1;

should have been:

    DenseMap<T*, unsigned> DM;
    for (auto &X : ...) {
      unsigned Size = DM.size();
      DM[&X] = Size + 1;
    }

Until r214242, this difference between compilers didn't matter.  In
r214242, `OrderMap::LastGlobalValueID` was introduced and compared
against IDs, which in GCC were off-by-one my expectations.

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for the Low Level
Virtual Machine, a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
