[C++0x patch] implement range-based for loops

[Rodrigo Rivas]

Hello, again.

Re-checking the patch, in gcc/cp/dump.c (cp_dump_tree):
Where it says:
+      dump_child ("init", RANGE_FOR_DECL (t));
Should be instead:
+      dump_child ("decl", RANGE_FOR_DECL (t));

Should I re-do the patch and send it again with these changes? Or is
it preferable to wait until more reviewing is done?
There isn't a hurry because my copyright assignment is still in progress...
