This commit updates to the latest isl development version. There is no specific
feature we need on the Polly side, but we want to ensure test coverage for the
latest isl changes.

Clang's been taught to warn on more things here (unused values when
calling pure functions and ignoring their result, for example).
It might be better to figure out how to have cmake compile these tests
without -Werror/without any warnings enabled. But this'll do for now & I
don't know enough about cmake to fix it any other way, or to understand
the tradeoffs in that space.

Refactor all ISL-related cmake build instructions into its own
CMakeLists.txt and build as a separate library.
This is useful to apply ISL-related build flags to ISL only and not to
Polly's files. Also, it the separation of both projects becomes clearer.
Proposed name of the library is Polly_isl. It is not "isl" to avoid
mix-up with potentially installed libisl.{a|so}.
Tested configurations:
- Windows with cmake 3.2
- Ubuntu with cmake 3.0.2
- Ubuntu with cmake 3.0.2 BUILD_SHARED_LIBS on
- Ubuntu with cmake 2.8.12.2 (LLVM minimum version)
- Ubuntu out-of-LLVM-tree
