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.
