For cases where we needed a foreach loop in reverse over a container,
we had to do something like
for (const GlobalValue *GV : make_range(TypeInfos.rbegin(),
TypeInfos.rend())) {
This provides a convenience method which shortens this to
for (const GlobalValue *GV : reverse(TypeInfos)) {
There are 2 versions of this, with a preference to the rbegin() version.
The first uses rbegin() and rend() to construct an iterator_range.
The second constructs an iterator_range from the begin() and end() methods
wrapped in std::reverse_iterator's.
