Trying r313138, https://chromium-review.googlesource.com/665341

I was going to say let's wait for Adrian's https://reviews.llvm.org/D37715 which should fix  issue 755841 , but rolls are relatively cheap.

Cool! I didn't realize that one was almost fixed.

I also don't think we should wait for it, but aim to roll twice.

More practice doing clang rolls for me! I'm all for it.

We need r313213 for the  Issue 764969  fix.

We need r313222 for  Issue 765004 .

Once we roll past r313078, I'm hoping that we'll be able to switch the default linker on Linux to lld.
