Previously isl always generated '<=' or '>='. However, in many cases '<' or '>'
leads to simpler code. This commit updates isl and adds the relevant code
generation support to Polly.

The "llvm.codegen" intrinsic patch is a patch to LLVM, which is used
to generate code for embedded LLVM-IR strings. In Polly, we use it
to generate ptx assembly text for GPGPU code generation.

Derive the maximal and minimal values of a parameter from the type it has. Add
this information to the scop context. This information is needed, to derive
optimal types during code generation.

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.

We just strip-mine the innermost dimension by the vector width. This does not
take into account if this dimension is parallel nor if it is constant.

The isl based routines implement a new interpretation of the Pluto algorithm
new interpretation. This patch requires a recent version of isl to be installed.
