Method to_base

crates/compiler-core/src/bytecode/instruction.rs:512–557

Map an INSTRUMENTED_* opcode back to its base variant. Returns `None` for non-instrumented opcodes, and also for `InstrumentedLine` / `InstrumentedInstruction` which are event-layer placeholders without a fixed base opcode (the real opcode is stored in `CoMonitoringData`). The returned base opcode uses `Arg::marker()` for typed fields — only the opcode byte matters since `replace_op` preserves th
