[PATCH] D125263: [CMake][MSVC] Compile with `/permissive-`

[Eli Friedman via Phabricator via llvm-commits]

> We are seeing failures in our internal Windows build with an older version of the Visual C++ compiler that I bisected back to this commit. The errors are all similar to this:

I don't see any obvious reason for this to fail, or be affected by /permissive-.  Can you attach and/or send me preprocessed source for the failing file?

-------------

I assume the issue with std::max was that "/permissive-" turns on two-phase lookup... but clang-cl and cl have slightly different views about what exactly two-phase lookup means.  So cl is fine, but clang-cl prints an error (and other platforms are fine because <algorithm> is somehow included anyway).
