20b78f8eef Store flags in bitfields instead of masking them into the pointer for the left child. This leads to some nice conceptually cleanups.

5db856d384 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.

9c1ca33ac3 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?

7ec2a31f14 Turns out llvm-gcc still uses SplitString with a vector. Add it back until I 
have a fix.

cdbc36f961 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.

090f279ac5 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.

c71c44ec7f Add accessors for the largest-magnitude, smallest-magnitude, and 
smallest-normalized-magnitude values in a given FP semantics.
Provide an APFloat-to-string conversion which I am quite ready to admit could
be much more efficient.

bc295111a1 pull destroy_range and uninitialized_copy up to the

c9b5e915c2 sink most of the meat in smallvector back from SmallVectorTemplateCommon 
down into SmallVectorImpl.  This requires sprinking a ton of this->'s in,
but gives us a place to factor.

19ee3f5216 substantial refactoring of SmallVector, now most code is in SmallVectorTemplateCommon, 
and there is a new SmallVectorTemplateBase class in between it and SmallVectorImpl.
SmallVectorTemplateBase can be specialized based on isPodLike.

b3db396df3 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.

587962c667 Remove isPod() from DenseMapInfo, splitting it out to its own 
isPodLike type trait.  This is a generally useful type trait for
more than just DenseMap, and we really care about whether something
acts like a pod, not whether it really is a pod.

8508c1f18e 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.

63e2201f3e Add an implementation of the delta debugging algorithm. 
- This is a pretty slow / memory intensive implementation, and I will likely
   change it to an iterative model, but it works.

2d2fb3f6ec Workaround PR5482, because all the gcc versions that I had were miscompiling StringRef: 
4.2.4, 4.3.4, 4.4.2.
The workaround is to use a local min/max implementation that takes an integer
param, and not a reference to integer param (like std::min does).
