0c6e0c25a1 Two NFC changes: 
- Add a DominanceInfo::dominates helper functions that takes two instructions,
  as analogues to the properlyDominates ones.
- Further generalize some SILBuilder code to be more defensive in the face
  of incorrect or partially constructed SIL instructions.

These are cleanups, NFC.

d5fd775703 master-next: Update DomTreeBuilder template declarations. 
The declarations that I moved into the header on master do not
match the versions for master-next. This just updates the header
to match the template instantiations in lib/SIL/Dominance.cpp.

b9f6e6b371 Remove llvm::DominatorBase templates to match LLVM r306713. 
The content from DominatorBase has been merged into DominatorTreeBase,
and DominatorBase has been removed.

9203283628 SILOptimizer: switch to NodeRef 
This adds the typedef and switches uses of NodeType * to NodeRef.  This is in
preparation for the eventual NodeRef-ization of the GraphTraits in LLVM.  NFC.

f9eab6243d Update LoopInfo for changes to LLVM. 
The two changes were:

1. I added a graphtraits implementation for a const
DomTreeNodeBase<SILBasicBlock>.
2. LoopInfoBase::Analyze() => LoopInfoBase::analyze().

6d9a7a1045 Helper class for visiting basic blocks in dominance order. 
It uses a worklist-based algorithm. In contrast to a recursive traversal algorithm,
it cannot cause a stack overflow for very deep dominator trees.

dd4f26c6dc It does seem to make non-generic assumptions about the node 
type, though;  I had to define a WriteAsOperand function and
add a front() method to SILFunction to get this to work.
Rip out my dominators implementation and replace it with
LLVM's.  I'd forgotten that LLVM's was actually generic.
