This commit adds an OpenACC test case (libgomp.oacc-fortran/pr95551-1.f90) related to ensuring variables in the offload table are streamed out correctly, complementing the existing OpenMP ‘target’ test case. It also replaces the original array assignment with an OpenACC ‘kernels’ construct to avoid gang-redundant execution.
