[PATCH] OpenMP threadprivate directive

[Doug Gregor]

  Fairly minor comments here. The typo-correction logic is the only thing I'd like to look at again; otherwise, this LGTM.

err_omp_var_const_addr is no longer used. It should be deleted.

----------------
Clang typically doesn't try to provide typo correction when what you've typed actually does name a declaration but is of the wrong kind. I'd rather see the "did you mean?" form of err_omp_expected_var_arg_suggest used as the diagnostic when DiagnoseEmptyLookup() does the correction, and just have "%0 does not refer to <something that can be threadprivate>) with a note pointing at the declaration that was found by lookup.
