Handle bundled terminators in isBlockOnlyReachableByFallthrough. Targets like SPARC and MIPS have delay slots and normally bundle the delay slot instruction with the corresponding terminator. Teach isBlockOnlyReachableByFallthrough to find any MBB operands on bundled terminators so SPARC doesn't need to specialize this function. llvm-svn: 199061

Codegen: Fix broken assumption in Tail Merge. Tail merge was making the assumption that a layout successor or predecessor was always a cfg successor/predecessor. Remove that assumption. Changes to tests are necessary because the errant cfg edges were preventing optimizations. llvm-svn: 273700
