Added support for machine specific constantpool values. These are useful for
...
representing expressions that can only be resolved at link time, etc.

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 :)

Add the actual constant to the hash for ConstantPool nodes. Thanks to
...
Rafael Espindola for pointing this out.

Switch to using SuperFastHash instead of adding all elements together. This
...
doesn't significantly improve performance but it helps a small amount.

Switch NodeID to track 32-bit chunks instead of 8-bit chunks, for a 2.5%

speedup in isel time.

RegNodes, and ValueNodes maps into the CSEMap.

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.
