What do people think about this patch, it is very mechanical.
A couple of thoughts, first, timings for C++ (once converted) at -O0
as chain influences time more than most, and I suspect we'd want all
languages bootstrapped and tested before any mid end backend code goes
in, just to be sure a front end isn't misusing any part of the tree
and it sure would be nice if the complier had hard types for those
places that used something like DECL_CHAIN to ensure it was a decl,
but, failing that, I'd hope that you could ensure that the
documentation reflects the new assert. For example, take
DECL_ARGUMENTS:
Also if we have don't have a decl in this place, it would ICE a little
latter, this
is just checking it earlier. Also I have not changed where the chain
is yet, just
the accessors and then more checking.
