This patch fixes walk_tree_1 to call the function on the TYPE_DECL, as we do
for other decls of a DECL_EXPR.
Where is that done exactly? The only case handled by DECL_EXPR is TYPE_DECL.
The only case handled specially is TYPE_DECL; other DECL_EXPRs fall
through to the default case, where we WALK_SUBTREE over all the operands
of the expression, which for DECL_EXPR is the decl.
I suppose it might be clearer to walk the decl for all DECL_EXPRs, then
have the special TYPE_DECL handling, then break instead of falling
through, though that doesn't get the tail recursion of the default case.
Thoughts?
