1. I'm sorry, but I had to revert r310489 and follow-up commits r310505,
r310519, r310537 and r310549 since it looks like the failures are accumulating.
The revert commit was r310580. The following run lines were failing for me
because of various assertion failures and file check errors:

2. I think that this test is starting to get a bit big, which makes it harder
to figure out what exactly is failing. Can you please use new test files in the
future patches?
3. Can you please figure out why your commit emails don't make it to the
cfe-commits.llvm.org mailing list? It's easier to follow the situation with the
commit emails.
Let me know if you need help figuring out the failures,
Alex
