This is a problem with --always-opt forcing optimization for functions that are too big. This cannot happen in production (without --always-opt).

commit 8c1234861c5829ec306cf19625741de48e5eec7d

[turbofan] Bailout from optimizations for large bytecode sizes (>128kB).

Turbofan can only handle 64K control inputs for merges. Such large
can only be created by functions with 64K jumps, so we limit the
bytecode size to the minimum size of bytecode arrays with 64K jumps.
