It seems hard to believe that the inliner relies on this to copy DECLs though, 
see the calls to remap_decl[s].  And note that remap_decl has had a special 
handling for DECL_ORIGINAL_TYPE of TYPE_DECLs since 2003.  Are you sure the 
problem is not that the TYPE_DECL is not attached to the enclosing BIND_EXPR?
