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.

Wasm frames are special in that they have a non-integer script id
in inspector. The way we treat script ids currently is a bit of a mess -
our runtime functions expected integer IDs while inspector has string
IDs (which contain integers, except for Wasm frames). This will need to
be cleaned up once more Wasm tests are added.
The meaning of line/column numbers has also changed; the old JS debug
API encoded the function index and byte offset into line/column numbers,
while inspector-based API actually translates into lines/columns in the
disassembly.

Unfortunately, there's currently no satisfying way of accessing scopes
of suspended generator objects through inspector. This CL implements
access to such scopes through runtime functions instead.

StepFrame is a combination of StepIn/StepOut, e.g. it breaks to the next
frame change. This is not part of the public API, but we want to keep it
for internal tests.

their names.
* Reconstruct values of Number, String, and Boolean classes.
* Adapt a couple of tests for API restrictions.

Stepping in a generator now behaves similar to stepping inside an
async function. Stepping in or next at a yield expression will result in
a break inside the same generator when we return to the generator.
Behavior of step-out does not change.

Adapted various tests to restrictions of inspector protocol:
* osr-typing-debug-change: Don't set function variable value.
* debug-evaluate-locals: Add variable introduced by eval, run typeof
inside evaluate().
* regress-419663: Don't set duplicate breakpoints.
* regress-crbug-465298: Compare against function name instead of value.
* regress-crbug-621361: Make evaluate return string results.
* debug-script: Various counts were off due to new way tests are called.
Added new inspector script type.
Breakpoints now contain the actual break position, and remote object
reconstruction has been extended a bit.

This adds access to the LiveEdit API object, frame.restart(), and
various breakpoint setters. The LiveEdit API still depends on the JS
debugging context and blocks its removal; but it should be removed
once LiveEdit is rewritten in the midterm.

This CL further extends the debug wrapper, migrates around 60 tests, and
removes a few tests that use functionality we will not support anymore.
In more detail:
* Removed tests that use:
* enable/disable individual breakpoints
* invocationText()
* the ScriptCollected event
* showBreakPoints
* evalFromScript (and similar)
* mirror.constructedBy and mirror.referencedBy
* event_data.promise()
* Some frame.evaluate uses were adapted since due to differences between
remote objects (inspector) and mirrors. For instance, exceptions are
currently not recreated exactly, since the inspector protocol does not
give us the stack and message separately. Other objects (such as
'this' in debug-evaluate-receiver-before-super) need to be explicitly
converted to a string before the test works correctly.
* Ensure that inspector stores the script before sending ScriptParsed and
ScriptFailedToParse events in order to be able to use the script from
within those events.
* Better remote object reconstruction (e.g. for undefined and arrays).
* New functionality in wrapper:
* debuggerFlags().breakPointsActive.setValue()
* scripts()
* execState.setVariableValue()
* execState.scopeObject().value()
* execState.scopeObject().property()
* execState.frame().allScopes()
* eventData.exception()
* eventData.script()
* setBreakPointsActive()

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.

We cannot generate debug events if JS execution is disallowed since
vital debugging logic is still implemented in JS. Return early from
Debug::OnException if that is the case.

This CL adds further support to the test wrapper. We are now able to
run almost all mjsunit/debug-step-* tests using the inspector backend.
debug-stepframe-* tests are not yet supported since inspector does not
know a 'frame' step type.
The interface has also been improved to be able to move these tests to
inspector mostly without modification.
