Fixes for 1324523008 which was reverted. (Due to GetUserDefaultLocaleName being available on Vista and later)
Original description:
Add sbox tests related to warming up of locales.
Warm up locales in LowerToken() after RevertToSelf() as existing warmup was not working on Win 8.1 x64.
Remove existing warmup which was done outside of LowerToken().
