RFR: 8253453: SourceFileInfoTable should be allocated lazily

[Claes Redestad]

Avoids allocating and clearing a 128Kb large ResourceHashTable eagerly on startup

It's only used when PrintInterpreter is enabled - which prints out the interpreter during bootstrap - so proper
synchronization seems excessive.

Testing: tier1, verified source line comments retained with `-XX:+PrintInterpreter`
