MSVC does not provide builtin support for alternative operator representations <https://en.cppreference.com/w/cpp/language/operator_alternative>.

Instead, their `#include <сiso646>` includes <https://github.com/microsoft/STL/blob/main/stl/inc/ciso646> `iso646.h`, which contains preprocessor definitions for these terms.

Generally, people, even LLVM project itself <https://github.com/llvm/llvm-project/blob/main/llvm/lib/DebugInfo/GSYM/LookupResult.cpp> do not expect their code to be compiled agains libcxx on Windows. This PR makes `#include <ciso646>` and `#include <iso646.h>` equavalent.
