traversing inverse register coalescing map.

7b714321df Move Split<...>() into DomTreeBase. This should make the #include's of DominatorInternals.h 
in CodeExtractor and LoopSimplify unnecessary.

52e2d83e65 Changed the return type of type-specific Allocate() methods to return 
void*.  This is hint that we are returning uninitialized memory rather
than a constructed object.

Patched ImutAVLTree to conform to this new interface.

869a3344f1 Added member template functions to MallocAllocator and 
BumpPtrAllocator that implement allocations that return a properly
typed pointer.  For BumpPtrAllocator, the allocated memory is
automatically aligned to the minimum alignment of the type (as
calculated by llvm::AlignOf::Alignment).

efd4a5144b Updated VC++ build system. 
Silenced some VC warnings.

I'm getting linker errors, though: unresolved externals:

llvm::Split<class llvm::BasicBlock *,struct llvm::GraphTraits<class llvm::BasicBlock *> >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)

and

llvm::Split<struct llvm::Inverse<class llvm::BasicBlock *>,struct llvm::GraphTraits<struct llvm::Inverse<class llvm::BasicBlock *> > >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)

Where are these defined?

f411b83c8c Return Expand from getOperationAction for all extended 
types.  This is needed for SIGN_EXTEND_INREG at least.
It is not clear if this is correct for other operations.
On the other hand, for the various load/store actions
it seems to correct to return the type action, as is
currently done.
Also, it seems that SelectionDAG::getValueType can be
called for extended value types; introduce a map for
holding these, since we don't really want to extend
the vector to be 2^32 pointers long!
Generalize DAGTypeLegalizer::PromoteResult_TRUNCATE
and DAGTypeLegalizer::PromoteResult_INT_EXTEND to handle
the various funky possibilities that apints introduce,
for example that you can promote to a type that needs
to be expanded.

67c18d5034 Document the fact that the verifier currently requires the 
top bit of a ValueType to be zero.  Enforce this by ensuring
an assertion failure if someone tries to create a ValueType
without this property.  I chose this minimal approach rather
than a more official integration of the notion of reserved
bits into ValueType because I'm hoping that the verifier will
be changed to no longer require this :)

af47b11b95 Initial infrastructure for arbitrary precision integer 
codegen support.  This should have no effect on codegen

getTypeToTransformTo, which maybe should be refactored
with a non-inline part for extended value types.
