This LGTM, although I am probably no the right one to review this. Erik, could
you lend a second pair of eyes?

src/objects.cc:7873: if (code()->kind() == Code::FUNCTION) {
Another kind that can appear here is Code::BUILTIN.
Builtins implemented in assembly have such kind.
 
Builtins implemented in javasript have kind Code::FUNCTION.

For example, d8 outputs the following for the EQUALS builtin implemented in
javascript:

--- Code ---
kind = FUNCTION
name = EQUALS
Instructions (size = 2076)
                  [ function compiled by full code generator
