3ec68f97ea Store flags in bitfields instead of masking them into the pointer for the left child. This leads to some nice conceptually cleanups.

b357e06f67 Introduce Twine::toStringRef, a variant of toVector which avoids the copy if the
twine can be represented as a single StringRef. Use the new methode to simplify
some twine users.

bf86e5df18 add new isSingleStringRef()/getSingleStringRef() methods to twine,
and use them to avoid a copy of a string in getNameWithPrefix in
the common case.  It seems like Value::setName and other places 
should use this as well?

d4f195999a Reimplement getToken and SplitString as "StringRef helper functions"
- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

cb89afc965 Add a SmallBitVector class, which mimics BitVector but uses only
a single pointer (PointerIntPair) member. In "small" mode, the
pointer field is reinterpreted as a set of bits. In "large" mode,
the pointer points to a heap-allocated object.

Also, give BitVector empty and swap functions.

And, add some simple unittests for BitVector and SmallBitVector.

4a5129c700 a few improvements:
1. Use std::equal instead of reinventing it.
2. don't run dtors in destroy_range if element is pod-like.
3. Use isPodLike to decide between memcpy/uninitialized_copy 
   instead of is_class.  isPodLike is more generous in some cases.

4bbf4ee149 Remove isPod() from DenseMapInfo, splitting it out to its own

more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

d01518630a Simplify this class by removing the result cache.
This change removes the DefaultConstructible
and CopyAssignable constraints on the template
parameter T (the first one).

The second template parameter (R) is defaulted to be
identical to the first and controls the result type.
By specifying it to be (const T&) additionally the
CopyConstructible constraint on T can be removed.

This allows to use StringSwitch e.g. for llvm::Constant
instances.

Regarding the other review feedback regarding performance
because of taking pointers, this class should be completely
optimizable like before, since all methods are inline and
the pointer dereferencing and result value caching should be
possible behind the scenes by the "as-if" rule.

2fe05d80d3 Workaround PR5482, because all the gcc versions that I had were miscompiling StringRef:

param, and not a reference to integer param (like std::min does).
