Support direct tuple access operators "tuple.N"
This patch adds tuple access expressions. If t is a tuple, its
N-th component can be retrieved with the syntax t.N. Of course,
the components are zero indexed. I believe the code also works
if 't' is a pointer to a tuple (but I have not checked this).
