This PR adds an initial implementation for the map modifiers close, present and ompx_hold, primarily just required adding the appropriate map type flags to the map type bits. In the case of ompx_hold it required adding the map type to the OpenMP dialect. Close has a bit of a problem when utilised with the ALWAYS map type on descriptors, so it is likely we'll have to make sure close and always are not applied to the descriptor simultaneously in the future when we apply always to the descriptors to facilitate movement of descriptor information to device for consistency, however, we may find an alternative to this with further investigation. For the moment, it is a TODO/Note to keep track of it.
The LLVM/Offload Subproject
The Offload subproject aims at providing tooling, runtimes, and APIs that allow users to execute code on accelerators or other "co-processors" that may or may not match the architecture of their "host". In the long run, all kinds of targets are in scope of this effort, including but not limited to: CPUs, GPUs, FPGAs, AI/ML accelerators, distributed resources, etc.
For OpenMP offload users, the project is ready and fully usable. The final API design is still under development. More content will show up here and on our webpage soon. In the meantime, people are encouraged to participate in our meetings (see below) and check our development board as well as the discussions on Discourse.
