Compiler [Optimizer]: Fix fatal error in docode().

The code generator complained about "F_PUSH_ARRAY unexpected in
this context." when evaluating top-level F_ARG_LIST nodes containing
F_PUSH_ARRAY nodes. This seems to be an old bug that has resurfaced
with the removal of the top_statement_label_dummy.

Fixes #10023.
