@alexfh Thanks for correcting the reviewers. I had no idea who to add so I used 
something like `git-suggest-reviewers`.



================
Comment at: lib/Format/Format.cpp:1958
   LangOpts.DeclSpecKeyword = 1; // To get __declspec.
+  LangOpts.CoroutinesTS = 1;
   return LangOpts;

SGTM. I'll make the change. 


================
Comment at: lib/Format/TokenAnnotator.cpp:589
       }
+      if (Style.isCpp())
+        if (CurrentToken && CurrentToken->is(tok::kw_co_await))
----------------

The `Style.isCpp()` should be unneeded now that the Coroutines TS keywords only 
parse when the style is Cpp.


================
Comment at: lib/Format/TokenAnnotator.cpp:2267
+      return true;
+    if (Right.is(tok::l_paren) && Left.is(tok::kw_co_await) &&
+        Left.Previous && Left.Previous->is(tok::kw_operator))
----------------

Not sure I have a test, I was probably mistaken adding this.

@djasper Assuming only one set of changes is needed, would they be better in 
`spaceRequiredBetween` or `spaceRequiredBefore`?


================
Comment at: lib/Format/UnwrappedLineParser.cpp:433
     case tok::kw___try:
+      assert(!Tok->is(tok::kw_co_await));
       if (!LBraceStack.empty() && LBraceStack.back()->BlockKind == BK_Unknown)

Sorry, I meant to remove it, I just couldn't when I left the comment as a 
reminder.
