[ms][dll] #27212: Generating of implicit special members should take into account MSVC compatibility version
Clang creates implicit move constructor/assign operator in all cases if
there is std=c++11. But MSVC supports such generation starting from
version 1900 only. As result we have some binary incompatibility.
