[PATCH] D70791: Workaround for MSVC 16.3.* pre-c++17 type trait linkage

[Reid Kleckner via Phabricator via cfe-commits]

rnk added a comment.

My version of cl.exe claims to have version 19.23.28107 and my headers are in Tools/MSVC/14.23.28105/include, and I see that this is fixed in xtr1common. is_integral_v and the helpers are defined with implicit template instantiations. There are no fully specialized template definitions in that header. So, my hope is that this problem will go away as users run the VS updater. Although, for buildbots and users such as myself who rarely start the IDE, that may take longer than we'd like.
