- Fortran OpenMP correctly handles POINTER array privatization.
- tldr
- Fortran `POINTER` attribute arrays with OpenMP `firstprivate` clauses now correctly maintain their association status instead of being deep-copied.

This commit corrects an issue where Fortran arrays with the POINTER attribute were deep-copied when used with an OpenMP firstprivate clause, instead of having their association status preserved. A new language hook, omp_array_data_privatize, differentiates these cases during OpenMP lowering. This ensures compliance with the OpenMP specification for POINTER variables, where new list items should receive the same association status as the original.
