The {JumpTableAssembler} should not include {wasm-code-manager.h}. It
only depends on assembler headers in {src/codegen}.
This removes the {flush_i_cache} parameter which is always set anyway,
removes the last include from {src/wasm} and updates the DEPS file to
forbid such includes for the future.

Currently, debugger pauses on async call schedule and then waits for Debugger.pauseOnAsyncCall
with parentStackTraceId to actually schedule the pause.
This CL combines these two steps:
- For local async tasks, it just stores m_taskWithScheduledBreak at the time of schedule,
to be able to pause once this task is run.
- For external async tasks, it plumbs "should_pause" boolean in V8StackTraceId from
the point of schedule to the point of execution, and schedules a pause once
externalAsyncTaskStarted is called with "should_pause" set to true.
This approach greatly simplifies the implementation, and reduced frontend to a single
"breakOnAsyncCall: true" parameter in Debugger.stepInto.
Drive-by: introduce hasScheduledBreakOnNextFunctionCall() to make
SetBreakOnNextFunctionCall management more robust.
Note: artificial pauses at async call schedule time are gone from test expectations -
we now only pause when user actually wants to pause, which makes protocol much simpler.

Case statements have a list of statements associated with them, but are

in this way removing ranges reported as uncovered between the final
break/return in a case and the next case (or end of function).

whether the value returned after calling @@iterator property is a valid

array.every():
for (var i = 0; i < kMemSize; i++) {
assertEquals(0, array[i]);
}
assertTrue(array.every((e => e == 0)));
The for-loop takes ~180s, every() takes ~19s.
Numbers above are for arm.debug build (simulator). On x64.debug builds
we can see a similar 10x improvement, from ~6s to ~400ms.

This CL changes how variables are resolved during debug evaluate.
We now re-parse the whole script when creating a ScopeIterator.
This gives us accurate scope information for all parent scopes of the
closure in which we stopped. Using this information, we build
blacklists of stack-allocated variables. Each context on the chain
in between the closure context up to the original native context is
wrapped in a debug-evaluate context with such a blacklist attached.
Variable lookup for debug-evalute contexts then works as follows:
1) Look up in the materialized stack variables (stayed the same).
2) Check the blacklist to find out whether to abort further lookup.
3) Look up in the original context.
Steps 1-3 is repeated for each debug-evaluate context, since they
mirror the original context chain.

When analyzing functions scopes with the script_scope as parent, don't
skip migrating unresolved variables upwards if we could still be inside
an arrow head, which means accesses to those variables will be
correctly context allocated.

It looks like the loop is there to create objects and trigger GC. It's
also tailored to Crankshaft, which was removed long ago.
This code currently times out on some arm bots, and it's hard to see
any value in it. Thus remove it.
