[clang][OpenMP] 6.0: detect privatization of array section/assumed-size array (#152786) According to the OpenMP 6.0 specification, array sections with no length and unknown size are considered assumed-size arrays. As of pull request https://github.com/llvm/llvm-project/pull/148048 these types of array sections are allowed and can be specified in clauses that allow array sections as list items. However, only two clauses explicitly allow array sections that are assumed-size arrays: - 'map' and 'use_device_addr'. The other clauses that accept array sections do not explicitly accept assumed-size arrays: - inclusive, exclusive, has_device_addr, in_reduction, task_reduction, reduction These cases should generate an error. See OpenMP 6.0 specification section 7.4 List Item Privatization, Restrictions, p. 222, L15 Assumed-size arrays must not be privatized For OpenMP 6.0, function getPrivateItem() now checks for array section list items that are assumed-size arrays and generates an error if they are not allowed for the clause. Testing - Updated LIT tests for assumed-size array sections to ensure these clauses generate an error: inclusive, exclusive, has_device_addr, in_reduction, task_reduction, reduction and that this clause is accepted (codegen test): use_device_addr - check-all - OpenMP_VV (sollve_vv)
