JIT: don't allocate promoted struct death vars map for clear or lookup (#19753)

Only allocate this map if we're adding something. Refactor clearing and
lookup to do minimal work if the map hasn't been allocated (and it won't
have been in debug / minopts).

Saves a tiny bit of throughput and memory.
