The __experimental macro tags a given exported function as being part of
the EXPERIMENTAL api. Use of this tag will cause any caller of the
function (that isn't removed by dead code elimination) to emit a warning
that the user is making use of an API whos stabilty isn't guaranteed.
It also places the function in the .text.experimental section, which is
used to validate the tag against the corresponding library version map
