Polly should now be compiled with CLooG 0c252c88946b27b7b61a1a8d8fd7f94d2461dbfd
and isl 56b7d238929980e62218525b4b3be121af386edf. The most convenient way to
update is utils/checkout_cloog.sh.
llvm-svn: 141251
The tool is called checkout_cloog.sh. We also update the get_started
documentation to include this tool. An older unfinished tool called
'get_cloog.sh' is removed to avoid confusion.
