1661ffa2eb 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.

92b45ad949 - Change AssignTopologicalOrder to return vector of SDNode* by reference.

90a25bcd6f Ugly hack! Add helper functions InsertInFlightSetEntry and
RemoveInFlightSetEntry. They are used in place of direct set operators to
reduce instruction selection function stack size.

db5b91f6a8 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.

7ed816f900 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.

the vector type itself needs to be decimated.
