Log:
Test to check optimizer's behavior in presense of debugging information.

If input.bc includes llvm.dbg intrinsics and llvm.dbg variables then
first.bc and second.bc in following should match. Otherwise debugging 
information is influencing the optimizer.                                                                                                                                              
$ opt input.bc -strip -std-compile-output -o first.bc                                                                                                                      
$ opt input.bc -std-compile-output -strip -o second.bc
