[PATCH 12/15] msvcrt: Swap the threadlocinfo pointers in setlocale().

[Piotr Caban]

From: Chip Davis <cdavis(a)codeweavers.com>

Do this instead of swapping their contents. This way, the result of
_get_current_locale(), which references the current threadlocinfo, won't
change after a setlocale() call.
