* Sort #includes, remove dupliates
* Use .zero to emit padding between struct elements * Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print * Print global variable identifiers next to initializer more nicely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7551 91177308-0d34-0410-b5e6-96231b3b80d8
