[Bug c/22278] gcc -O2 discards cast to volatile

According to Joseph Myers, the question is whether this counts as "access" to
a volatile object, which is implementation defined (6.7.3#6). However,
extend.texi doesn't answer this, so I'll reopen it as a documentation problem.
We could then either document it does not constitute an access, or change
the behavior and state that it does.
