1) Enable tests that use `import Dispatch` on Linux. Add substitution `%import-libdispatch` that needs to be used for all cross-platform tests (i.e., tests that are intended to be run on other platforms than Darwin) that do `import Dispatch` or enable thread sanitizer. 2) Make sure as many existing Dispatch and TSan tests as possible run on Linux. Mark tests that would require substantial work with `UNSUPPORTED: OS=linux-gnu`. 3) Add integration-style Swift test that shows that TSan finds a simple race when using `Dispatch.async` incorrectly. A more complete test suite for TSan's libdispatch support lives on the LLVM/compiler-rt side. rdar://problem/49177535
