Riccardo Mori 44596fe6a9 [Polly][Isl] Use the function unsignedFromIslSize to manage a isl::size object. NFCI ... 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. In the official interface the type `isl::size` cannot be casted to an unsigned without previously having checked if it contains a valid value with the function `isl::size::is_error()`. For this reason two helping functions have been added: - `IslAssert`: assert that no errors are present in debug builds and just disables the mandatory error check in non-debug builds - `unisgnedFromIslSIze`: cast the `isl::size` object to `unsigned` Changes made: - Add the functions `IslAssert` and `unsignedFromIslSize` - Add the utility function `rangeIslSize()` - Retype `MaxDisjunctsInDomain` from `int` to `unsigned` - Retype `RunTimeChecksMaxAccessDisjuncts` from `int` to `unsigned` - Retype `MaxDimensionsInAccessRange` from `int` to `unsigned` - Replaced some usages of `isl_size` to `unsigned` since we aim not to use `isl_size` anymore - `isl-noexceptions.h` has been generated by e704f73c88 No functional change intended.
