9f21c2daf4 Remove the temporary option: -no-isel-fold-inflight

ff5a88b62e Added a temporary option -no-isel-fold-inflight to control whether a "inflight" 
node can be folded.

7bb910dbe7 Fix the updating of the machine CFG when a PHI node was in a successor of 
the jump table's range check block.  This re-enables 100% dense jump tables
by default on PPC & x86

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.

553050adcb Make sure both member variables are initialized in the default constructor 
for SDOperand. This gets rid of numerous warnings in lib/CodeGen and
lib/Target when compiled with GCC 4.0.2

3d518334b9 SelectionDAGISel can now natively handle Switch instructions, in the same 
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary
search tree of basic blocks.  The new approach has several advantages:
it is faster, it generates significantly smaller code in many cases, and
it paves the way for implementing dense switch tables as a jump table by
handling switches directly in the instruction selector.

This functionality is currently only enabled on x86, but should be safe for
every target.  In anticipation of making it the default, the cfg is now
properly updated in the x86, ppc, and sparc select lowering code.
