  [clang] P2266 implicit moves STL workaround

This patch replaces the workaround for simpler implicit moves
implemented in D105518.

The Microsoft STL currently has some issues with P2266.

Where before, with -fms-compatibility, we would disable simpler
implicit moves globally, with this change, we disable it only
when the returned expression is in a context contained by
std namespace and is located within a system header.
