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.

BUG=v8:5203

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.

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.

52ff3ae48b [builtins] implement RunMicrotasks pump as a code stub
- Implement RunMicrotasks in CSA to prevent a potentially large number
  of jumps between C++ and JS code while consuming te queue. Appears to
  provide a ~60% speedup in microtask-heavy code, which from limited
  testing appears to scale linearly.

  The code-stub microtask pump bails out to the old C++ microtask pump
  if it encounters a CallHandlerInfo microtask, and remains in C++ for
  the remainder of the queue (returning to the JS/stub implementation
  after the bailed out queue is exhausted).

- Add a variation of JSEntryStub which enters the new RunMicrotasks code
  stub.

- Add a new RunMicrotasks helper to Execution, which uses the
  RunMicrotasks entry stub.

48c1cb9746 [inspector] introduce way to get full stored async stack
If async stack is longer then max depth, we add externalParent as id,
client can fetch next max depth async stacks by Debugger.getStackTrace.

653a9e2bd3 [inspector] introduced universal Debugger.pauseOnAsyncCall
If protocol client needs to make step-into async call:
- pause before async call using any Debugger agent capabilities,
- call Debugger.stepInto with breakOnAsyncCall flag,
- wait for Debugger.paused event, this event will contain
  asyncCallStackTrace if async call is scheduled,
- call Debugger.pauseOnAsyncCall on each known target,
- resume execution in current debugger by Debugger.resume.

885a5669aa Reland [inspector] introduced stackTraceId and externalAsyncTask API
Sometimes we need to capture stack trace on one debugger and use it
later as a parent stack on another debugger (e.g. worker.postMessage).

This CL includes following addition to our protocol and v8-inspector.h:
  - added Runtime.StackTraceId, this id represents stack trace captured
    on debugger with given id,
  - protocol client can fetch Runtime.StackTrace by
    Runtime.StacKTraceId using Debugger.getStackTrace method,
  - externalParent field is added to Debugger.paused event, it may
    contain external parent stack trace,
  - V8Inspector::storeCurrentStackTrace captures current stack trace
    and returns V8StackTraceId for embedder this id can be used as
    argument for V8Inspector::externalAsyncTaskStarted and
    V8Inspector::externalAsyncTaskFinished method. Any async stack
    trace captured between these calls will get passed external stack
    trace as external parent. These methods are designed to be called
    on different debuggers. If async task is scheduled and started on
    one debugger user should continue to use asyncTask* API,
  - Debugger.enable methods returns unique debuggerId.
