This reverts commit r279086, reapplying r279084. I'm not sure what I
ran before, because the compile failure for ADTTests reproduced locally.
The problem is that TestRev is calling BidirectionalVector::rbegin()
when the BidirectionalVector is const, but rbegin() is always non-const.
I've updated BidirectionalVector::rbegin() to be callable from const.
Original commit message follows.

As a follow-up to r278991, add some tests that check that
decltype(reverse(R).begin()) == decltype(R.rbegin()), and get them
passing by adding std::remove_reference to has_rbegin.
I'm using static_assert instead of EXPECT_TRUE (and updated the other
has_rbegin check from r278991 in the same way) since I figure that's
more helpful.

This reverts commit r243567, which ultimately reapplies r243563.
The fix here was to use std::enable_if for overload resolution. Thanks to David
Blaikie for lots of help on this, and for the extra tests!
Original commit message follows:
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.

This reverts commit r243563.
The GCC buildbots were extremely unhappy about this. Reverting while
we discuss a better way of doing overload resolution.
