Remove the unused OMP_CLAUSE_DEVICE_RESIDENT

Hi!
While working on something else, I came across the following. Cesar, can
you please verify that this is really dead code in the Fortran front end,
which currently is the only producer of OMP_CLAUSE_DEVICE_RESIDENT?
Also, I noticed that the Fortran front end never creates OMP_CLAUSE_MAP
with GOMP_MAP_LINK or GOMP_MAP_DEVICE_RESIDENT -- how is OpenACC declare
working at all? Cesar, if this is not a simple question to answer,
please file a GCC PR, for somebody to have a look later.
Jakub, if the following patch is OK, should I also clean it up on release
branches as applicable, or just on trunk?
