This removes the {flush_i_cache} parameter which is always set anyway,

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.

The point of this test is to check for OOB access traps, the read/write
of the entire backing buffer is not useful to this test, and causes the
test to be really slow, especially on arm simulator. This change cuts

TNodified:
 * EmitCreateShallowArrayLiteral
 * EmitCreateShallowObjectLiteral

Also propagated the TNodification of AllocationSite. Previously it was
used a lot with nullptr, and that changed to {}.

Sort inactive live ranges by their assigned register and by their next
start. This allows {FindFreeRegistersForRange} to stop the search earlier
and significantly reduces compile time for some test cases.

This enables using TNode types without including code-assembler.h,
which is useful when generating CallInterfaceDescriptors.

As a drive-by, this moves TNode from v8::internal::compiler to
v8::internal. It's only used outside of the compiler anyway.

Case statements have a list of statements associated with them, but are
not blocks, and were hence not fixed-up correctly for code coverage.
This CL also applies the fix-up to the "body" of case statements,
in this way removing ranges reported as uncovered between the final
break/return in a case and the next case (or end of function).

Drive-by: Add optional pretty printing to code coverage test results.
