With this particular pattern of passes requiring one another and LoopSimplify
and CallGraph, pass manager never terminates.

I have confirmed this with gcc 4.1.2 and 4.2.4 against llvm svn revision 68820.

To recreate this bug,

Compile the attached C++ source code to a shared library

Run opt:

opt -load ./libBug.so -after input.bc -o output.bc
