This removes most of the reproducer instrumentation. It stills relies on the LLDB_RECORD_* macros for logging.
I'm planning a few subsequent patches:
- Remove the LLDB_RECORD_RESULT macros
- Rename the LLDB_RECORD_ macros to LLDB_API_LOG or something similar
- Update lldb-instr to only generate the LLDB_API_LOG macros
