  Changed paths:
    M llvm/lib/CodeGen/TargetLoweringObjectFileImpl.cpp
    M llvm/test/CodeGen/PowerPC/aix-lower-jump-table.ll

  Log Message:
  -----------
  [XCOFF][AIX] Put each jump table in an independent section if -ffunction-sections is specified

If a function is in a unique section, putting all jump tables in
 .rodata will prevent functions that have a jump table to get
garbage collect by the linker.
Therefore, we need to put jump table into a unique section as well.
