Section symbols exist as an optimization: instead of having multiple relocations point to different symbols, many of them can point to a single section symbol. When that optimization is unused, a section symbol is also unused and adds no extra information to the object file. This saves a bit of space on the object files and makes the output of llvm-objdump -t easier to read and consequently some tests get quite a bit simpler. llvm-svn: 239045
