Insert a memory release barrier (function version).
Please refer to SDL_MemoryBarrierRelease for details. This is a function
version, which might be useful if you need to use this functionality from a
scripting language, etc. Also, some of the macro versions call this
function behind the scenes, where more heavy lifting can happen inside of
SDL. Generally, though, an app written in C/C++/etc should use the macro
version, as it will be more efficient.
Threadsafety:
Obviously this function is safe to use from any thread at any
time, but if you find yourself needing this, you are probably
dealing with some very sensitive code; be careful!
