JIT-Less V8

But in some situations it can be desirable to run V8 without allocating executable memory:

V8’s new JIT-less mode is intended to address these points. Essentially, V8 switches into an interpreter-only mode based on our existing technology: all JS user code runs through the Ignition interpreter, and regular expression pattern matching is likewise interpreted. Here, JIT-less mode is roughly on-par and only shows a 6% slowdown in JS execution compared to a standard V8 configuration.
