Run codegen dce pass for all targets at all optimization levels. Previously it's 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

Delete dead PHI machine instructions. These can be created due to type legalization even when the IR-level optimizer has removed dead phis, such as when the high half of an i64 value is unused on a 32-bit target. I had to adjust a few test cases that had dead phis. This is a partial fix for Radar 7627077. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95816 91177308-0d34-0410-b5e6-96231b3b80d8
