This patch does not implement anything new, but simply separates
OpenACC 'enter data' and 'exit data' into two libgomp API functions.
The original API name is kept for backward compatibility, but no
longer referenced by the compiler.
The previous implementation assumed that it would always be possible
to infer which kind of pragma it was dealing with from the context,
but there are a few exceptions, and I want to add one more:
zero-length arrays.
By cleaning this up I will be free to add the new feature without the
reference counting getting broken.
This update fixes a new conflict and updates the patterns in a number of
testcases that were affected.
OK to commit?

OpenACC: Separate enter/exit data APIs
Move the OpenACC enter and exit data directives from using a single builtin
to having one each. For most purposes it was easy to tell which was which,
from the directives given, but there are some exceptions. In particular,
zero-length array copies are indistiguishable, but we still want reference
counting to work.
