dc08cd56c4 Replace EquivalenceClasses with a custom-built data structure. Many common 
operations (like findProperties) should be faster, at the expense of
unionSets being slower in cases that are rare in practise.

Don't erase a dead Instruction. This fixes a memory corruption issue.

the PredicateSimplifier is skipped in make check anyways.

3b53c4ee91 Implement unrolling of multiblock loops. This significantly improves the 
utility of the LoopUnroll pass.

Also, add a testcase for multiblock-loop unrolling.

fd90dd5d55 For PR872: 
Shrinkify LLVM's footprint by removing the analyze tool and moving its
functionality into the opt tool. THis eliminates one of the largest tools
from LLVM and doesn't make opt much bigger because it already included
most of the analysis passes.  To get the old analyze functionality pass
the -analyze option to opt. Note that the integeration here is dead
simple. The "main" of analyze was just copied to opt and invoked if the
-analyze option was given. There may be opportunities for further
integration such as removing the distinction between transform passes
and analysis passes.

To use the analysis functionality, if you previously did this:
  analyze $FNAME -domset -disable-verify
you would now do this:
  opt -analyze $FNAME -domset -disable-verify
Pretty simple.
