Thomas Schwinge ddb25eb9ca [PR92726, PR92970, PR92984] [OpenACC] Clarify 'acc_delete' etc. for 'NULL'-in, non-present data, or size zero
PR92970 "OpenACC 2.5: 'acc_delete' etc. on non-present data is a no-op" is an
actual bug fix, and the other ones are fall-out, currently undefined behavior.

	* oacc-mem.c (delete_copyout): No-op behavior if 'lookup_host'
