1919804 - Remove JS Tracer automatic stop on infinite loop

Status: RESOLVED FIXED

(DevTools :: Debugger, enhancement)

Description

[Alexandre Poirot [:ochameau]]

The early implementation of the JS Tracer was too slow to handle large call stack depth.
For this a custom logic was stopping it when hitting large call stack.

We should now remove this confusing behavior, as the JS Tracer is performant enough to handle large stacks.
The infinite loops are still going to be ultimately stopped by the JS engine, around 11k depth on my setup.

Instead, only rely on JS engine infinite loop detection.
The JS Tracer can now handle fine call stack with large depth.
