IS_CONST operands don't have to be separated. Use reference-counting instead of duplication.

- with opcache all IS_CONST operands are not refcounted (scalars, interned strings or immutable arrays)
- without opcache IS_CONST operands are not shared between processes or threads and may use common reference counters
