de964dbe57 Introducing an event loop mechanism for d8.
This mechanism ensures APIs like wasm async complete their work, 
without requiring use of natives (%APIs).

The mechanism is similar to the one used in content_shell,
which should allow us to easily port tests in that environment.

7371c34b6b Use --opt instead of --crankshaft in tests.
1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and 
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

267115da42 [parser] avoid complex for-loop desugaring when possible
let/const declarations in "standard" C-style for-loops have
some complex desugaring to accommodate the case where loop
loop variables may be captured. This slows down the baseline
performance of for-loops with let variables.

This change attempts to avoid this desugaring if it's known that
the loop variable is not captured at any point. A side effect of
this change is that let/const loop variables, when not captured
within the loop body, are not necessarily shown in the debugger,
similar to other stack-allocated vars.

980448dfcd [Compiler] Remove CompileBaseline and three tier pipeline.
Since we no longer support the ignition-staging configuration 
any longer,  we can retire the three tier pipeline and the
CompileBaseline functionallity.

We still need support for JSFunction self healing due to
liveedit (which for --no-turbo might end up replacing a
forced Ignition function with a FCG function) - we can
remove this once we remove --no-turbo support.

e27d18c943 [debugger] tuned StepNext and StepOut at return position
Proposed behaviour:
- StepNext at return position go into next function call (no changes with current behavior, but implemented in v8::Debug instead of hack on inspector side);
- StepOut at return position go into next non-current function call.

We need this to have better stepping in cases with native functions, blackboxed functions and/or different embedder calls (e.g. event listeners).

New behavior could be illustrated with two examples (for more see stepping-with-natives-and-frameworks test):
- let's assume that we've blackboxed callAll function, this function just takes its arguments and call one after another:
var foo = () => 1;
callAll(foo, foo, () => 2);
If we break inside of first call of function foo. Then on..
..StepNext - we're able to reach second call of function foo,
..StepOut - we're able to reach () => 2 call.

- let's consider case with native function:
[1,2,3].map(x => x * 2)
If we break inside of first callback call, then with StepNext we can iterate through all calls of callback, with StepOut we go to next statement after .map call.

Implementation details:
- when we request break we schedule step-in function call for any step action at return position and for step-in at any position,
- when we request StepOut at return position - we mark current function as needed-to-be-ignored inside of PrepareStepIn(function) call,
- when we request StepOut at not return position - we set break at return position and ask debugger to just repeat last step action on next stepping-related break.

f774d8c56f [Flags] Add negation implications for --turbo negative so --no-turbo works.
Once we enabled --turbo by default we need to turn all the implications
off with --no-turbo as well. Chrome sets flags in V8 using SetFlagFromString,
which enforces the implications each time it is called. Therefore, if --turbo
is enabled by default, and an unrelated flag is set, the turbo implications are
enabled but not later disabled if we set --no-turbo. To fix this, add negative
implications as well.

3f47c63ded [liveedit] reimplement frame restarting.
Previously, when restarting a frame, we would rewrite all frames
between the debugger activation and the frame to restart to squash
them, and replace the return address with that of a builtin to
leave that rewritten frame, and restart the function by calling it.

We now simply remember the frame to drop to, and upon returning
from the debugger, we check whether to drop the frame, load the
new FP, and restart the function.

6d42c4504a [complier] Enable parallel eager inner function compilation with compiler dispatcher.
Enable enqueueing of eager inner function compilation onto the compiler
dispatcher. This enables these tasks to be performed in parallel to
compilation of the outer functio (only for Ignition functions).
We currently synchronize to ensure all inner function compilations
 are complete before executing the outer function - future work will
allow outer function execution to happenin parallel to inner function
compilation.

passes all the tests in the file.
Mark fast/js/string-capitalization as failing with no_i18n.

Relanding after revert because the failure was taken care of
by Adam's CL at https://codereview.chromium.org/2597543002 .

3rd langing after a crash is taken care of in

In addition to the previous version of this CL (PS #4) that landed and
reverted, drop String.prototype.to(Locale){Upper,Lower}Case from the
whitelist of built-in functions for side-effect-free-debugging.

9eec1c8617 [debug-wrapper] Migrate wasm/frame-inspection test
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.

a0e9160066 [debug-wrapper] Implement StepFrame through runtime
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.

416e423fdb [debugger] step-next across yield should not leave the generator.
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.

1834ab7246 [debug-wrapper] Adapt tests, breakpoint.actual_location
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.

b06c4ce5a6 [debug-wrapper] Further extend the debug wrapper
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()

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.

ea48d0942a [debugger] Further stepping support in test wrapper
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.
