I think I'd prefer (for now) to suffix the functions with _41 instead of 1
(and we'll see if we can come up with better names when async support is
added).  Do we need to change GOMP_target_update though (at least right
now)?  I mean, the construct only allows to and from clauses, not the map
clause, and those don't really have an always modifier, nor release/delete
semantics etc., so at least for now I think using the current
GOMP_target_update should be ok.
