694481ee01 Eliminate SelectNodeTo() and getTargetNode() variants which take more than 
3 SDOperand operands. They are replaced by versions which take an array
of SDOperand and the number of operands.

5892d47a62 Change the use_list to be a smallvector instead of a vector. This reduces 
isel time from 6.79s to 5.53s (22%) on kc++ with a release build on ppc.
Go smallvector! :)

2fa6d3b1fc 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.

213a16c637 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 :)

f06f35e30b 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%.

a5682853b9 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.

37efe67645 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.
