[perl #123870] runtime trie debug output

Fixed by d0bec20370:

    [perl #123870] fixup trie runtime debug output
    
    The trie_words av may not exist if -Dr was not enabled at compile time,
    so we must be more defensive for debug output at runtime.

It's probably not worth adding as part of the regular test suite, but there might be some value in a run of the existing re tests with -Dr enabled at run time but not compile time. I'll try that if I get time.
