[PATCH 0/5] amdgcn: Improve TImode support

[Julian Brown]

This patch series extends TImode support for AMD GCN (see e.g. PR96306
and PR95730). This fixes several test failures that appear at present,
and enables use of a 128-bit integer "omp_depend_kind" for OpenMP 5.0.

Tested with offloading to AMD GCN. Further commentary on invididual
patches.

Thanks,

Julian
