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.

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 :)

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++

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%.

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

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.

RET chain, value1, sign1, value2, sign2

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.
