Code is split off of gomp_init_device into the new gomp_init_tables:

..., and a new function gomp_init_dev_tables added to call both of them:

libgomp: Restore code that initializes the address mapping tables in
GOMP_target_update.
libgomp/
* target.c (GOMP_target_update): To initialize, call
gomp_init_dev_tables instead of gomp_init_device.
With Intel MIC offloading (emulation), this fixes cases of "#pragma omp
declare
target" of variables, followed by "#pragma omp target update to([...])"
before
any "#pragma omp target" or "#pragma omp target data" is called:
