CALLER_SETUP_ARG removes an empty keyword hash from argv
...only when a "remove_empty_keyword_hash" flag is specified.
After CALLER_SETUP_ARG is called, `ci->flag & VM_CALL_KW_SPLAT` must not
be used. Instead. use `calling->kw_splat`. This is because
CALLER_SETUP_ARG may modify argv and update `calling->kw_splat`, and
`ci->flag & VM_CALL_KW_SPLAT` may be inconsistent with the result.
