Hello,
The documentation for the __sync builtins calls them legacy but doesn't clearly
say that the __atomic builtins should be prefered. This patch adds a statement
to that effect. It also simplifies some of the text and weakens a suggestion of
future change in the the __syncs behaviour.
Tested by looking at the html and info files.
Ok for trunk?

* doc/extend.texi (__sync Builtins): Simplify some text. Update
details about implementation. Make clear preference for __atomic
builtins. Reduce possibility of future change.
