This appears to have broken at least the windows build bots due to
compile errors in the predicate that didn't simply supress the overload.
I'm not sure what the fix is, and the bots have been broken for a long
time now so I'm just reverting until Michael can figure out a fix.

MSVC's STL has a bug in `std::equal()`: it asserts on nullptr iterators,
causing a block revert in r215981. This works around that by re-writing
`ArrayRef::equals()` to do the work itself.

checking whether the ArrayRef is equal to an explicit list of arguments.
This is particularly easy to implement even without variadic templates
because ArrayRef happens to be homogeneously typed. As a consequence we
can use a "clever" wrapper type and default arguments to capture in
a single method many arguments as well as *how many* arguments the user
specified.
Thanks to Dave Blaikie for helping me pull together this little helper.
Suggestions for how to improve or generalize it are of course welcome.
I'll be using it immediately in my follow-up patch. =D

The slice(N, M) interface is powerful but not concise when wanting to
drop a few elements off of an ArrayRef, fix this by adding a drop_back
method.

Doesn't make sense to restrict this to BumpPtrAllocator. While there
replace an explicit loop with std::equal. Some standard libraries know
how to compile this down to a ::memcmp call if possible.

Summary:
Made UnicodeCharSet a class, perform validity checking inside its
constructor instead of each isCharInSet call, use std::binary_search instead of
own implementation.
This patch comes with a necessary change in clang (sent separately).

They mostly mirror the ArrayRef constructors, with two exceptions:
* There's no function mirroring the default constructor because it wouldn't have any parameters to deduce the right ArrayRef<T> from.
* There's an explicit SmallVector<T> overload in addition to the SmallVectorImpl<T> overload. Without it, the single-element overload would try to create an ArrayRef<Smallvector<T> > because it's a better match according to the overloading rules. (And both overloads are used in the current tree, so neither is redundant)

ExtractValueInst APIs to use ArrayRef: a new constructor taking a
(begin, end) range, and operators == and != for element-wise comparison.

representing a constant reference to ValType. Normally this is just
"const ValType &", but when ValType is a std::vector we want to use
ArrayRef as the reference type.

use in many places where we pass a pointer and size to abstract APIs
that can take C arrays, std::vector, SmallVector, etc. It is to arrays
what StringRef is to strings.
