Changed profiling method for ImmutableMap to once again just use its

Modified ImutAVLTree:
(1) changed ComputeHash() to ComputeDigest() and
(2) changed Profile() to use the computed digest and
(3) modified insertion of IMutAVLTree into the FoldingSet owned by
the ImutAVLTreeFactory object to use profiling instead of computing
a direct hash. This fixes a bug where our abuse of the FoldingSet would
not work when the FoldingSet was resized.

Modified node creation of ImutAVLTree to do a hash lookup for an existing
...
node in the FoldingSet of nodes held by the Factory object. If we
we find a node with a matching hash, we do a full structural comparison.
Nodes are also now inserted into the FoldingSet only when we mark them
Immutable, as their children can change during intermediate-rebalancing.
The 'Profile' method for ImutAVLTree is no longer used when looking up
existing ImutAVLTrees with a given set of contents; instead the Profile method
is used by other clients that wish to insert such a tree into a folding set.
This means that we are not using FoldingSet in ImutAVLTreeFactory in the way
it was intended, but instead are using it as an opaque hashtable.

I don't see how NodeUpdated can be called with a
...
ReadyToProcess node - add an assertion to check
this. Add an assertion to NodeDeleted that checks
that processed/ready nodes are indeed not deleted.
It is because they are never deleted that none of
the maps can have a deleted node as the source of
a mapping. It does however seem to be possible in
theory to have a deleted value as the target of a
mapping, however this has not yet been spotted in
the wild. Still mulling on what to do about this.
[The theoretical situation is this: a node A is
expanded/promoted/whatever to a newly created node
B. Thus A->B is added to a map. When the subtree
rooted at B is legalized it is conceivable that B
is deleted due to RAUW on a node somewhere above
it].

Change the 'global modification' APIs in SelectionDAG to take a new
...
DAGUpdateListener object pointer instead of just returning a vector
of deleted nodes. This makes the interfaces more efficient (no more
allocating a vector [at least a malloc], filling it in, then walking
it) and more clean. This also allows the client to be notified of
nodes that are *changed* but not deleted.

Generalize the SDOperand->SDOperand form of

SelectionDAG::ReplaceAllUsesWith to handle replacement of
an SDOperand with *any* sdoperand, not just one for a node with
a single result. Note that this has a horrible FIXME'd hack in it
to work around PR1975. This should be removed when PR1975 is fixed.

SDIsel processes llvm.dbg.declare by recording the variable debug information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc.
...
Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes.
For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time.
