[Polly][Isl] Refactoring IslAstInfo::getBuild() and IslAstInfo::IslAstUserPayload::Build to use isl++. NFC
Polly uses algorithms from the Integer Set Library (isl), which is a library written in C and which is incompatible with the rest of the LLVM as it is written in C++.
Changes made:
- Refactoring the method `IslAstInfo::getBuild()`
- `IslAstInfo::IslAstUserPayload.Build` now uses C++ types instead of C types
- Removing destructor of `IslAstInfo::IslAstUserPayload`
