These two patches follow on from: https://gcc.gnu.org/pipermail/gcc-patches/2020-June/548908.html
and: https://gcc.gnu.org/pipermail/gcc-patches/2020-June/549178.html The first patch has been rethought somewhat -- we can factor out the common parts of goacc_enter_datum/goacc_enter_data_internal and goacc_exit_datum/goacc_exit_data_internal into two new functions. Doing it this way avoids overloading the return type of the "enter data" function (i.e. returning NULL for multiple mappings -- I really don't like that "overloading"), and is less problematic wrt. the profiling API, I think. The second patch has been adjusted to account for the first (using the newly factored-out helper functions as appropriate), and I've also fixed some locking thinkos and added code to fix the new struct-3-1-1.c test. Currently re-testing with offloading to NVPTX -- the patches have been tested in combination with others previously though. OK now?
