If we can reland this patch, it should fix this new clang bug:

The ppc64be stuff seems like only someone with hardware will be able to debug 
it.
For `clang/test/CXX/temp/temp.arg/temp.arg.template/p3-2a.cpp`, you are saying 
you can reproduce that locally?
The timeout seems like it could be flakiness or something unrelated.
The thinlto failures... I'm not sure either, but again it's PPC64, so it could 
be flakiness.

It seems like it would be best to alert the owners of those bots and reland and 
get new results, assuming things pass on less exotic bot configurations.
