patacca f482497c38 [Polly][Isl] Use isl::set::tuple_dim, isl::map::domain_tuple_dim and isl::map::range_tuple_dim. NFC
This is part of an effort to reduce the differences between the custom C++ bindings used right now by polly in `lib/External/isl/include/isl/isl-noxceptions.h` and the official isl C++ interface.

Changes made:
 - Use `isl::set::tuple_dim` instead of `isl::set::dim` and `isl::set::n_dim`
 - Use `isl::map::domain_tuple_dim` instead of `isl::map::dim`
 - Use `isl::map::range_tuple_dim` instead of `isl::map::dim`
 - isl-noexceptions.h has been generated by this 45576e1b42

Note that not all the usage of `isl::{set,map}::dim` where replaced

Polly - Polyhedral optimizations for LLVM
-----------------------------------------
http://polly.llvm.org/

Polly uses a mathematical representation, the polyhedral model, to represent and
transform loops and other control flow structures. Using an abstract
representation it is possible to reason about transformations in a more general
way and to use highly optimized linear programming libraries to figure out the
optimal loop structure. These transformations can be used to do constant
propagation through arrays, remove dead loop iterations, optimize loops for
cache locality, optimize arrays, apply advanced automatic parallelization, drive
vectorization, or they can be used to do software pipelining.
