From 6f6c06adc1c0338e0125e7d5785b43223493f114 Mon Sep 17 00:00:00 2001
From: Will Dietz <w@wdtz.org>
Date: Thu, 2 Mar 2017 16:51:32 -0600
Subject: llvm4.0: Rename "4.0" (and _40) to "4" (and _4).

This reflects upstream versioning change, and allows
us to replace 4.0 with 4.1 (which is now a minor revision)
without changing the attribute name.

Thanks to @vcunat for the idea.
