Zhongxing Xu e31a8ebfdc Fix a serious bug. 
When initialized, the index of the ElementRegion was unsigned. But the index
value of the ArraySubscriptExpr is signed. This inconsistency caused the value
of the array element retrieved to be UnknownVal despite it was initialized to
symbolic.

This is only a hack. Real fix of this problem is required.

Zhongxing Xu 3698bdb417 Enable the GRStateManager to do something when we finish a path. For example, 
the ConstraintManager can print its internal state before its solver instance is
destroyed.

Chris Lattner e9f6c355bf rewrite RecursivelyDeleteTriviallyDeadInstructions to use a more efficient 
formulation that doesn't require set lookups or scanning a set.

Chris Lattner d4b5ba615e remove some weirdness that came from the LSR code that has 
nothing to do with dead instruction elimination.  No tests in
dejagnu depend on this, so I don't know what it was needed for.

of small cleanups.

Chris Lattner 98d89d1b1b Make jump threading substantially more powerful, in the following ways: 
1. Make it fold blocks separated by an unconditional branch.  This enables
   jump threading to see a broader scope.
2. Make jump threading able to eliminate locally redundant loads when they
   feed the branch condition of a block.  This frequently occurs due to
   reg2mem running.
3. Make jump threading able to eliminate *partially redundant* loads when
   they feed the branch condition of a block.  This is common in code with
   lots of loads and stores like C++ code and 255.vortex.

This implements thread-loads.ll and rdar://6402033.

Per the fixme's, several pieces of this should be moved into Transforms/Utils.
