Summary: The previous offloading entry type did not fit the current use-cases very well. This widens it and adds a version to prevent further annoyances. It also includes the kind to better sort who's using it. The first 64-bytes are reserved as zero so the OpenMP runtime can detect the old format for binary compatibilitry.

Non-comprehensive list of changes in this release

|
=================================================
|
|
|
|
Device Runtime
|
|
--------------
|
|
- Changed the OpenMP DeviceRTL to use 'generic' IR. The
|
|
``LIBOMPTARGET_DEVICE_ARCHITECTURES`` CMake argument is now unused and will
|
|
always build support for AMDGPU and NVPTX targets.
|
|
- Updated the offloading entry format but retained backwards compatibility with
|
|
the old format.
