only run for x86 with fastisel. I've found it being very effective in eliminating some obvious dead code as result of formal parameter lowering especially when tail call optimization eliminated the need for some of the loads from fixed frame objects. It also shrinks a number of the tests. A couple of tests no longer make sense and are now eliminated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95493 91177308-0d34-0410-b5e6-96231b3b80d8
