Chris Lattner 8c02c3f41a Compile: 
%tmp152 = setgt uint %tmp144, %tmp149           ; <bool> [#uses=1]
        %tmp159 = setlt uint %tmp144, %tmp149           ; <bool> [#uses=1]
        %bothcond2 = or bool %tmp152, %tmp159           ; <bool> [#uses=1]

To setne, not setune, which causes an assertion fault.

Nate Begeman 4ca2ea5b43 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.
