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.

When disabling simpler implicit moves in MSVC compatibility mode as
a workaround in D105518, we forgot to make the opposite change and
enable regular (P1825) implicit moves in the same mode.
As a result, we were not doing any implicit moves at all. OOPS!
This fixes it and adds test for this.
This is a fix to a temporary workaround, there is ongoing
work to replace this, applying the workaround only to
system headers and the ::stl namespace.

The Microsoft STL currently has some issues with P2266.
We disable it for now in that mode, but we might come back later with a
more targetted approach.
