This series of patches implement two tightly-knit OpenMP features: the
`dispatch` construct and the `adjust_args` clause to the `declare variant`
directive. `adjust_args` can only be used if the `dispatch` selector appears in
the `match` clause. The "interoperability requirement set" and the `append_args`
clause are out of scope.
In practice, this is mostly useful to transparently convert host pointer
arguments into device pointers when the function is offloaded.
All three front-ends have been tested on an x86_64 Linux machine, as well as
offloading on an AMD Instinct MI210 (gfx90a) GPU.
Paul-Antoine Arras (7):

OpenMP: C++ front-end support for dispatch + adjust_args
OpenMP: common C/C++ testcases for dispatch + adjust_args
OpenMP: Fortran front-end support for dispatch + adjust_args
OpenMP: update documentation for dispatch and adjust_args
