Run SimplifyLibCalls near the beginning, not at the end.  It is now run at the same moment as in llvm-gcc.  Also, run StripDeadPrototypes at the end, just before running DeadTypeElimination. This may be useful when doing LTO.  Note that llvm-gcc runs StripDeadPrototypes but not DeadTypeElimination.
