[issue32616] Significant performance problems with Python 2.7 built with clang 3.x or 4.x

Is there anything we (the CPython developers) can do about this? 

If I read the issue correctly clang 5.x generates faster binaries than clang 3.x and 4.x.  If that is indeed the issue there's probably not much we can do about this. 

BTW. I'm -1 on building the installer with anything but the compiler included in Xcode (and it would be nice to build with a recent version of Xcode to use an up-to-date compiler and SDK)
