This avoids the extra redirection through the closure function, which
does not need to be loaded otherwise during closure calls in this mode,
and thus removes another runtime dependency on the closure function in
bare instructions mode.
In non-bare mode, CODE_REG is populated with the code object for the
function, so caching wouldn't change the number of loads there.
This does not increase the size of closure objects, as there was
already a free word in them due to object alignment.
TEST=Existing tests.
