9c9583a2f2 inspector: speedup InspectorTest.logMessage
Current implementation might take significant amount of time to
traverse big message. We can reuse builtin JSON.stringify replacer
feature to achieve big performance boost.

1e250a75e4 [wasm] fix source maps for relative path
For wasm modules with non-absolute sourceMappingURL, the source needs
to be empty so that devtools can look for the source map at the origin
of the module.

215608f453 debug-evaluate: do not return JSGlobalObject instead of JSGlobalProxy
DebugEvaluate contains code since 2009 that bypasses JSGlobalProxy and
returns JSGlobalObject when result of expression is global proxy.
This behavior may be dangerous:
- JSGlobalObject does not perform security checks,
- some parts of V8 code do not ready for JSGlobalObject, e.g.,
  SetHashAndUpdateProperties function will crash on DCHECK if we will
  try to store JSGlobalObject to map.

At the same time it looks like there is no any valid use case for it.

1b3b808a54 inspector: find magic comment using V8 scanner
Inspector tries to provide sourceURL and sourceMappingURL for scripts
with parser errors. Without this CL we convert source of each script
to inspector string and search for magic comment there. Some web sites
use pattern when they get some data from network and constantly try to
parse this data as JSON, in this case we do a lot of useless work.

So we can parse magic comments on V8 side only for compilation errors
(excluding parse JSON errors), to do it we can reuse scanner by running
it on each potential comment.

dbfcc4878a [inspector] added V8InspectorClient::resourceNameToUrl
Some clients (see Node.js) use platform path as ScriptOrigin.
Reporting platform path in protocol makes using protocol much harder.
This CL introduced V8InspectorClient::resourceNameToUrl method that
is called for any reported using protocol url.
V8Inspector uses url internally as well so protocol client may generate
pattern for blackboxing with file urls only and does not need to build
complicated regexp that covers files urls and platform paths on
different platforms.

ec06732236 [utils] Change ReadFile interface
ReadFile returned a Vector with ownership transfer, i.e. the client
needed to call Dispose to free the memory. This CL changes the interface
to return a std::string instead, which manages ownership. As it turns
out, there is only one user of ReadString that sometimes calls an API
function which expects to take ownership of its Vector argument.

313bc6d43f [inspector] remove deprecated console methods
As per https://github.com/whatwg/console/issues/27#issuecomment-289312546
and https://bugs.chromium.org/p/chromium/issues/detail?id=706804 we're
leaving the console timeline/timelineEnd methods out of the specification
and testing that implementations do not expose them (relevant WPTs at
https://github.com/web-platform-tests/wpt/blob/master/console/console-tests-historical.any.js).
Their implementations should be removed from Chrome, one of the last
implementers of these legacy methods. The same goes for markTimeline, as
it is deprecated in Chrome and not being included in the spec.

21c0d77e15 [async] Optimize await and AsyncFromSyncIterator
Simplify the promise wrapping in await and
%AsyncFromSyncIteratorPrototype%.next/return/throw to reuse the PromiseResolve
primitive. Now await takes 1 tick instead of 3 on the microtask queue.

This is a step towards avoiding materializing function_ altogether if we deoptimize. Typically we only need the SharedFunctionInfo.

Currently we enable instrumentation if debugger is active. With this
approach we can not:
- capture async stack when debugger is disabled,
- avoid async instrumentation overhead when debugger is enabled and
  async stacks are disabled.

49c4ac7753 [inspector] added Runtime.installBinding method
A lot of different clients use console.debug as a message channel from
page to protocol client. console.debug is a little slow and not
designed for this use case.

This CL introduces new method: Runtime.installBinding. This method
installs binding function by given name on global object on each
inspected context including any context created later.
Binding function takes exactly one string argument. Each time when
binding function is called, Runtime.bindingCalled notification is
triggered and includes passed payload.

Binding function survives page reload and reinstalled right after
console object is setup. So installed binding can be used inside
script added by Page.addScriptToEvaluateOnNewDocument so client may do
something like:
Runtime.installBinding({name: 'send'});
Page.addScriptToEvaluateOnNewDocument({source: 'console.debug = send'});
.. navigate page ..

In microbenchmark this function is ~4.6 times faster then
console.debug.

b6c9086ca1 [inspector] reworked async stack instrumentation for async functions
New intstrumentation consists of:
- kAsyncFunctionSuspended when async function is suspended on await
  (called on each await),
- kAsyncFunctionFinished when async function is finished.

Old instrumentation was based on reusing async function promise.
Using this promise produces couple side effects:
- for any promise instrumentation we first need to check if it is
  special case for async function promise or not - it requires
  expensive reading from promise object.
- we capture stack for async functions even if it does not contain
  awaits.
- we do not properly cancel async task created for async function.

New intsrumntation resolved all these problems as well as provide
clear mapping between async task and generator which we can use later
to fetch scope information for async functions on pause.

6d87d95785 [inspector] use interrupt for pause only as last resort
With this CL we use interrupt for pause in two cases:
- when we process Debugger.pause on interruption,
- when we would like to break as soon as possible after OOM.
In all other cases, e.g. for async step into we use break
on function call by calling StepIn debugger action.

In mentioned cases we should not actually use interrupt as well:
- Debugger.pause in this case scheduled using interrupt and we
  may just break right now without requesting another interrupt,
  unfortunately blink side is not ready,
- we should use more reliable way to break right after near OOM
  callback, otherwise we can get this callback, increase limit,
  request break on next interrupt, before interrupt get another
  huge memory allocation and crash.

There are couple advantages:
- we get much better break locations for async stepping
  (see inspector tests expectations),
- we can remove DEBUG_BREAK interruption
  (it should speedup blackboxing with async tasks, see
  removed todo in debug.cc for details)
- it is required preparation step for async step out,
  (see https://chromium-review.googlesource.com/c/v8/v8/+/1054618)

ea7499f5da [generators] Store parameters in the generator object.
Currently, we context allocate all parameters for generators.

With this CL, we keep arguments on stack (unless they escape to inner
closure) and copy them between the stack and the generator's register
file on suspend/resume. This will save context allocation in most cases.

Note: There is an asymmetry between suspend and resume.
- Suspend copies arguments and registers to the generator.
- Resume copies only the registers from the generator, the arguments
  are copied by the ResumeGenerator trampoline.

7a2c371383 [debug] introduced runtime side effect check
This CL demonstrates minimum valuable addition to existing debug evaluate
without side effects mechanism.
With this CL user can evaluate expressions like:
[a,b] // create any kind of temporary array literals
[a,b].reduce((x,y) => x + y, 0); // use reduce method
[1,2,3].fill(2); // change temporary arrays

The core idea: any change of the object created during evaluation without
side effects is side effect free. As soon as we try to store this temporary
object to object existed before evaluation we will terminate execution.

Implementation:
- track all objects allocated during evaluation and mark them as temporary,
- patch all bytecodes which change objects.

d452a7f63a [inspector] queryObjects() should take objectGroup
Now, 'queryObjects' takes an optional 'objectGroup' argument,
allowing the frontend to release the response value.

This is important because each call produces a new Array, which
could not be released before.

Reason for revert: Speculative revert as win32/64 debug seems to
hang after this:
https://build.chromium.org/p/client.v8/builders/V8%20Win32%20-%20debug/builds/13691

6af30f41e4 Use String16Builder.appendUnsignedAsHex for hashes
The debugger script implementation had its own way to write
uint32_t values to a string as hex values. This removes the
custom code and uses a shared implementation in String16Builder
instead.

The observable effect is that script hashes are now lower-case
and the character sequence is reversed for each 8-character
pair.

910f45fa8d Reland: [Compiler] Use CompilationCache for StreamedScript compilation.
Previously GetSharedFunctionInfoForStreamedScript didn't either check the
compilation cache or put the result of compilation into the compilation
cache. This would mean future compiles would need to re-parse / compile
the same script even if the isolate had already seen it. This CL
fixes this.

Also refactors the compilation pipelines to ensure we call debug->OnAfterCompile()
for all script compiles even when loading from a cache.

6db8a9c079 [inspector] cleanup old failed to parse anonymous scripts
We already cleanup these scripts on frontend side. It is crucial to
cleanup them on backend side as well, since some web applications use
following logic: get some data from network, add this data to buffer,
try to parse buffer using JSON.parse. On each unsuccessfull JSON.parse
we get another scriptFailedToParse event.

Frontend logic of discarding scripts: https://goo.gl/FDtaWK

Some idea of smarter logic here: track what script ids are reported
using protocol and cleanup only script ids which reported not only as
part of scriptFailedToParse event.

2d889aa9a4 Reland "[esnext] load iterator.next only once at beginning of iteration"
https://github.com/tc39/ecma262/pull/988 gained concensus during the
september 2017 TC39 meetings. This moves the load of the "next" method
to the very beginning of the iteration protocol, rather than during
each iteration step.

This impacts:

- yield*
- for-of loops
- spread arguments
- array spreads

In the v8 implementation, this also affects async iteration versions of
these things (the sole exception being the Async-From-Sync iterator,
which requires a few more changes to work with this, likely done in a
followup patch).

This change introduces a new AST node, ResolvedProperty, which can be used
as a callee by Call nodes to produce the same bytecode as Property calls,
without observably re-loading the property. This is used in several
AST-desugarings involving the iteration protocol.

5b9adade64 [proxy] Set [[ProxyTarget]] to null during revocation
Before this, only the [[ProxyHandler]] was set to null during revocation
of the Proxy through either the v8::Proxy::Revoke() or the
Proxy.revocable() API. To be consistent with the spec, the Proxy's
target is set to null as well. This change should not be observable
through JS, since the check for if the Proxy is revoked should always
use the handler. But the changed value is exposed through the public
v8::Proxy::GetTarget() API, which is used by the inspector API and
Node.js.

Also included is a much more comprehensive test for Inspector's support
for Proxy, which prior to this commit did not work as intended.

bf4cc9ee15 [esnext] load iterator.next only once at beginning of iteration
https://github.com/tc39/ecma262/pull/988 gained concensus during the
september 2017 TC39 meetings. This moves the load of the "next" method
to the very beginning of the iteration protocol, rather than during
each iteration step.

This impacts:

- yield*
- for-of loops
- spread arguments
- array spreads

In the v8 implementation, this also affects async iteration versions of
these things (the sole exception being the Async-From-Sync iterator,
which requires a few more changes to work with this, likely done in a
followup patch).

This change introduces a new AST node, ResolvedProperty, which can be used
as a callee by Call nodes to produce the same bytecode as Property calls,
without observably re-loading the property. This is used in several
AST-desugarings involving the iteration protocol.

9f7d440e98 [test] Check output on the worker process.
I added additional exception logging in the execution.py since
errors in processing results were really difficult to debug.

There is a problem on Windows with class serialization when
it comes from dynamically loaded module. To fix it I moved all
output processors to the tools/testrunner/outproc/ and import
them in test/*/testcfg.py.

71605b3ea4 [test] Move has unexpected output to outproc.
Expected outcomes optimized to serialize [PASS] as None.

Keeping expected outcomes inside output processors should be
optimized in the future. Few possible optimizations:
- separate classes for tests that are expected to PASS - done as
an example in mozilla test suite.
- cache output processors inside testcase.
- share output processors between copies of the same test - needs
some updates to the create_variant to update outproc only if
expected outcomes changed.

Add an easy way to preview ArrayBuffer as a typed array. This change
will always allow previewing ArrayBuffer instances as Uint8Array and
Int8Array. ArrayBuffer instances that have even length will allow
Int16Array preview and ArrayBuffers that have length divisible by 4 will
allow Int32Array previews.
