[Clang][OpenMP] Added the support for target data nowait

[tianshilei1992]

Summary

Previously we added support for target nowait, but target data nowait
has not been supported yet. In this patch, target data nowait will also be
wrapped into a task.

[tianshilei1992]

Fixed a major issue and one test case

[jdoerfert]

LGTM

[tianshilei1992]

Rebased and fixed one test case

[tianshilei1992]

Fixed a rebase error

[tianshilei1992]

Fixed a rebase issue

[tianshilei1992]

Rebased (again) to involve the reversion of another patch that can cause clang crash

[tianshilei1992]

Fixed all failed test cases

[tianshilei1992]

The two failed test cases should have nothing to do with this patch. Will merge this patch.
