[PATCH] D103772: [clang-cl] Reenable /Zc:twoPhase by default if targetting MSVC 2017 Update 3 or newer

[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

It was reverted due to build failures, but it didn't reland because it's not the default in cl.exe after all. So we shouldn't make it the default in clang-cl either.
