LLVM backend needs to use `-globalopt` explicitly
While -O1 and -O2 includes a -globalopt pass, for reasons I don't entirely understand the location of the pass is such that not all aliases are eliminated. My ghc-7.8 branch includes a patch fixing this (as well as removing ARM from the dynamic linking blacklist)[1].
