b8ae2249a4 [tests] Fix assertFalse(exception) anti-pattern
Some debugging tests relied on the following anti-pattern:

 let exception = false;

 try {
   /* ... some code that may throw on test failure ... */
 } catch (e) {
   exception = e;
 }

 assertFalse(exception);

This may be problematic if a falseish value is thrown.

2bf71f888f [ignition/turbo] Perform liveness analysis on the bytecodes
Replaces the graph-based liveness analyzer in the bytecode graph builder
with an initial bytecode-based liveness analysis pass, which is added to
the existing loop extent analysis.

Now the StateValues in the graph have their inputs initialised to
optimized_out, rather than being modified after the graph is built.

b32ee40de8 [debug-wrapper] Conditional breaks, locals, evaluate, scopes
This CL adds support for:
* conditional breaks in setBreakpoint,
* locals in frame.local{Count,Name,Value},
* evaluation on a frame in frame.evaluate,
* and more detailed scope information in scopeObject.

Uses of several functions that are not covered by the
inspector protocol and are only used in tests have been removed.

Local handling has been modified to also include arguments as locals.
Inspector differs in this regard from our FrameDetails in that
arguments are always shown as locals. Argument-related functions
were removed.
