[ignition] Fix building lookup graph when search depth is 0 In some (rare) cases, the context depth passed to a dynamic variable lookup can be zero. In these cases, the fast path for the lookup (i.e. load from context or global) can always be taken, as there is no need to search the current context. However, with no slow path checks, the bytecode graph builder had a null environment for the slow path, causing segfaults when this graph was built. This patch adds a null check for the slow path environment, and skips building the slow path if the environment is null.

[flags] Rename --opt to --turbofan To be consistent with the all the other tiers and avoid confusion, we rename --opt to ---turbofan, and --always-opt to --always-turbofan.
