David Rowley 8d29d45d9b Fix assert failure in expand_grouping_sets
linitial_node() fails in assert enabled builds if the given pointer is
not of the specified type.  Here the type is IntList.  The code thought
it should be expecting List, but it was wrong.

In the existing tests which run this code the initial list element is
always NIL.  Since linitial_node() allows NULL, we didn't trigger any
assert failures in the existing regression tests.

There is still some discussion as to whether we need a few more tests in
this area, but for now, since beta2 is looming, fix the bug first.
