f2fe13f663 [inspector] don't call clearAllBreakpoints
This call from inspector side is redundant, V8 will clear all breakpoints on removing debug delegate in v8::internal::Debug::Unload method.

In any case for correct support of multiclient we need to clear breakpoints in V8DebuggerAgentImpl::disable method.

793053fd76 [coverage] Don't skip collection if invocation_count is zero
Function-granularity coverage skips functions that are both uncovered
and have an uncovered parent. This optimization needs to be tweaked once
block coverage and incremental collection is in play, as it is possible
to have a function with invocation_count == 0 (i.e. uncovered at
function granularity) that still has relevant block-granularity
coverage.

6b0bf1659e [inspector] move SetScriptSource call to native
To avoid using debugging context and debugger-script.js on inspector side we can move SetScriptSource call to v8::internal::Debug. Theoretically we can move live edit implementation to native completely but since it will be reimplemented it looks redundant.

c5e9416b1d [inspector] move stack trace and scope inspection to native
This CL moves us much closer to the point where we can remove debugger-script.js and usage of debugger context from inspector.
There are three main parts left:
- managing breakpoints,
- inspecting stack and scopes (this CL),
- LiveEdit.

In this CL I moved all stack/scope inspection to native. As side effect running debugger and inspector tests are 10-20% faster (it's significant since not all of tests requesting break).

This is dependent on a DevTools frontend patch to accept these new subtypes:

a8176a530c [ignition] removed nop bytecode
Nop bytecodes are required only for break locations in debugger. Since nop bytecode doesn't change program state we can remove all of them.

There are at least two changes which this CL produce:
- we don't provide break position when we load local variable (still provide when load variable from global),
- we don't provide break position for statements without actual break positions (e.g. "a;") - these expressions should be super rare and user always can set breakpoint before or after this statement.

0896586083 [inspector] improve return position of explicit return in non-async function
Goal of this CL: explicit return from non-async function has position after
return expression as return position (will unblock [1]).

BytecodeArrayBuilder has SetStatementPosition and SetExpressionPosition methods.
If one of these methods is called then next generated bytecode will get passed
position. It's general treatment for most cases.
Unfortunately it doesn't work for Returns:
- debugger requires source positions exactly on kReturn bytecode in stepping
  implementation,
- BytecodeGenerator::BuildReturn and BytecodeGenerator::BuildAsyncReturn
  generates more then one bytecode and general solution will put return position
  on first generated bytecode,
- it's not easy to split BuildReturn function into two parts to allow something
  like following in BytecodeGenerator::VisitReturnStatement since generated
  bytecodes are actually controlled by execution_control().
..->BuildReturnPrologue();
..->SetReturnPosition(stmt);
..->Return();

In this CL we pass ReturnStatement through ExecutionControl and use it for
position when we emit return bytecode right here.

So this CL only will improve return position for returns inside of non-async
functions, I'll address async functions later.

8b5b444a4c [async-await] desugar Await in BytecodeGenerator
This includes several changes. From most to least interesting:

- No longer implement AwaitExpressions using a do-expression.
- Reduces frame-size of async generators by not allocating temporary
  variables to hold results of Await epxressions.
- Streamline and reduce generated bytecodes for Await.
- Debugger no longer emits a debug::kCallBreakLocation breakpoint for
the JS-builtin call performed for Await, and instead only emits such
a breakpoint if the operand of Await is actually a call.
- Push fewer parameters to Await* builtins, using the receiver for the
  first parameter (possible now that the CallRuntime invocation not
  part of the AST).
- Adds a new Await AST node. No new members or anything, but it seemed
  palatable to avoid having `if (is_await())` in a number of
  VisitSuspend functions.

8d921ca7f3 [turbofan] Remove --turbo shorthand for --turbo-filter.
This removes the --turbo flag and solely relies on the filter pattern
provided via --turbo-filter when deciding whether to use TurboFan. Note
that disabling optimization wholesale can still be done with --no-opt,
which should be used in favor of --no-turbo everywhere.

Also note that this contains semantic changes to the TurboFan activation
criteria. We respect the filter pattern more stringently and no longer
activate TurboFan just because the source contains patterns forcing use
of Ignition via {AstNumberingVisitor::DisableFullCodegenAndCrankshaft}.

1541f422a7 [coverage] Expose block coverage through inspector
This piggy-backs on top of existing precise and best-effort coverage to expose
block coverage through the inspector protocol.

Coverage collection now implicitly reports block-granularity coverage when
available.  A new 'isBlockCoverage' property on Inspector's FunctionCoverage
type specifies the granularity of reported coverage.

For now, only count-based block coverage is supported, but binary block
coverage should follow soon.

Support is still gated behind the --block-coverage flag.

701d79d08a [inspector] introduced console.context
console.context(name:string) method returns console instance, this console instance fully implements console interface (including fact that any method can be called without console as receiver).
Protocol.Runtime.consoleAPICalled notification contains additional context:string field:
- "anonymous#unique-id" for any method call on unnamed console context,
- "name#unique-id" for any method call on named console context.

console.count and console.timeEnd have context as a scope.
console.clear clear all messages regardless on what context instance it was called.

console calls is ~10% slower with this CL since we need to store and then fetch console_context_id and console_context_name from function object.
We recently (in April) made console calls twice faster so 10% doesn't sound critical and existing of console.log call in hot code is problem by itself.

Found multiple issues (added TODOs for them):
- isPaused() check is global, so one can resume from another session/context group
  without receiving 'paused' notification;
- setBreakpointsActive flag is global affecting all sessions and context groups;
- max async call stack depth is global, and should be per context group.

6f69e3ceca [inspector] removed break location right before suspension in async function
In current implementation in expressions like await foo() we have break location right after foo call and before actual await.
And we additionally have a lot of other statement locations because of do scope.

Let's move async debugging closer to sync debugging and introduce only one break location for await - before awaited function call.

fb6a094db5 [inspector] moved var initialization break location before init expression (reland)
This CL improves break locations for expressions like 'var a = <expr>'. Without CL we use <expr> position as break location for initialization statement, with this CL we use position of first character after '=' as position.
Benefits (see test for details):
 - only one break in expressions which includes mix of property lookup and calls, e.g. var p = Promise.resolve().then(x => x * 2),
 - removed redundant break location for expressions like: let { x, y } = { x: 1, y: 2}.
