28369b8d7d Make getNodeValueTypes methods public.

8e8d9a3358 Add a new getNode() method that takes a pointer to an already-intern'd list
of value-type nodes.  This avoids having to do mallocs for std::vectors of
valuetypes when a node returns more than one type.

fe1fd00ce8 Add code to resize the CSEMap hash table. This doesn't speedup codegen of
kimwitu, but seems like a good idea from a "avoid performance cliffs" standpoint :)

7b1362fa52 Start eliminating temporary vectors used to create DAG nodes. Instead, pass
in the start of an array and a count of operands where applicable.  In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap.  In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.

I updated a lot of code calling getNode that takes a vector, but ran out of
time.  The rest of the code should be updated, and these methods should be
removed.

We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.

It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

be2fc7b875 Eliminate some malloc traffic by allocating vectors on the stack. Change some
method that took std::vector<SDOperand> to take a pointer to a first operand
and #operands.

This speeds up isel on kc++ by about 3%.

1661ffa2eb Revamp the "CSEMap" datastructure used in the SelectionDAG class. This
eliminates a bunch of std::map's in the SelectionDAG, replacing them with a
home-grown hashtable.

This is still a work in progress: not all the maps have been moved over and the
hashtable never resizes.  That said, this still speeds up llc 20% on kimwitu++
with -fast -regalloc=local using a release build.
