Actually precedence parsing is not a big job, incrementally what I did for my
patch was just a matter of
1) making a single map of all the productions instead of the per-function maps
we have currently
2) making cp_parser_binary_expression use it, still keeping the recursive call
and passing around the precedence we are interested in
3) turn recursion into an explicit stack
4) optimize to eliminate unneeded (simulated) recursion

It would be nice if the wiki were used to track in-house CodeSourcery projects.
 It looks like Jeffrey and I duplicated work, and we almost did the same on the
tree class codes projects (and I'm not mocking CodeSourcery's work, I'm just
reading the wiki and using common sense on where to optimize the compiler).
