38de91a5da Solaris/OpenBSD/FreeBSD: [heap] Uncommit unused large object page memory.
Port d61a5c376b

Original commit message:

    As a first step I uncommit the memory on the main thread. Also
    to measure impact and stability of that optimization. In a
    follow-up CL, the uncommitting should be moved on the concurrent thread.

c52685a516 gdb-v8-support.py: Fix old style print statement
Since python3 does not use the old print statement, it may not be able
to load gdb-v8-support.py script in gdb as below:

  (gdb) source tools/gdb-v8-support.py
    File "tools/gdb-v8-support.py", line 170
      print result
                 ^
  SyntaxError: Missing parentheses in call to 'print'

This fixes print statement for both python2 and python3.

2f6be682ac Parser: Report use counts once per feature
Reporting use counts by invoking a callback once per occurrence has
a large overhead cost in certain situations, for example when it needs
to be dispatched to a different thread (which is the case for Web Workers).

Parsing large scripts can produce a lot of occurrences (strict/sloppy mode
once per function).

Chromium (the only known user of UseCounters so far) does not actually care
about number of occurrences, but simply whether they happened at least once.
This commit changes behavior to report features at most once, which dramatically
improves performance for impacted use cases, and should not affect the only
known real world usage.

6336cc6b2b Fix testing of the VEX.L (128/256-bit) flag in the x64 disassembler
The current code for testing the VEX.L flag, indicating whether
128-bit or 256-bit registers are being accessed, was erroneous
and always returned true (i.e. indicated 128-bit registers).

This patch fixes this behaviour and checks the flag correctly.

26f617f1bc Optimize JSON stringifying when replacer and space are falsey.
Most libraries use `JSON.stringify` with all three arguments [1] to allow for
configuration, even if `replacer` and `space` are falsey, causing the
optimized native stringifying to be missed. This commit allows for the common
case where `replacer` and `space` are not used to be fast.

b6c9b70356 Make handle ctors explicit
Without this change, the v8::Local<> constructor will be picked up by the
compiler as an option for an implicit cast for any pointer type.  This leads
to bad error messages when accidentally passing an erroneous pointer type to
a function wanting a Local<> (complains about a pointer assignment in Local<>'s
constructor as opposed to a bad type for the parameter of the function being
called) and also causes ambiguity errors where none should exist when calling
overloaded functions (for example a function taking either a std::string or a
v8::Local<v8::Script> cannot be called with a const char * because the compiler
sees both types as being constructable with a const char *).

aeb8073c4a Add Isolate::DiscardThreadSpecificMetadata method to embedder API.
If many threads use the same Isolate (or many Isolates) and then
terminate, their PerIsolateThreadData objects are never cleaned
up, resulting in a slow memory leak and, worse, the
PerIsolateThreadData chain getting larger and larger, adversely
affecting performance.

In this situation, embedders will now be encouraged to apply
DiscardThreadSpecificMetadata against any Isolate a thread is
done with, especially if the thread is about to terminate.

Note that it is harmless to run DiscardThreadSpecificMetadata
against an Isolate for which a thread has no thread data and
per-Isolate thread data can be reestablished if a thread starts
using an Isolate again after running DiscardThreadSpecificMetadata
against it.

It is, however, an embedder error to run
DiscardThreadSpecificMetadata against an Isolate in thread with a
Locker for the Isolate in the stack or against an Entered Isolate.

This change cannot cause any change in behavior in existing apps
as the only added coded can only be reached via the new
DiscardThreadSpecificMetadata method.

Section 8.10.5 9a specifies that a property descriptor cannot both have

ab9898980e Don’t smash globals used by the test helper itself.
Since https://codereview.chromium.org/366103005 the promise tests null out
various globals, to ensure the promise implementation doesn’t itself rely
on functions patchable by monkeys.

Unfortunately, doing so breaks test assertion failures which rely on
those globals.

This isn’t the ideal solution, but does improve the current state.

ddb5c2d999 Make NumberFormat use the ICU currency data, fix bug in NumberFormat
NumberFormat previously just used a min of 0 digits after the decimal and a max of 3. This CL changes it so that we use the ICU currency data, and set the min and max to the number of numbers after the decimal point for each currency.

This CL also fixes a small bug where if the minimum fraction digits is above 3 but the maximum fraction digits isn't set, then it returns with only three numbers after the decimal point.

d05cb6b30f Revert of Added constructor call on object in InstantiateObject method (patchset id:80001 of https://codereview.chromium.org/1137693003/)
Reason for revert:
[Sheriff] This breaks layout test expectations:
http://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2032/builds/437

See:
https://storage.googleapis.com/chromium-layout-test-archives/V8-Blink_Linux_32/437/layout-test-results/fast/dom/create-element-after-stack-overflow-pretty-diff.html

Please land a needsmanualrebaseline change on the blink-side before relanding this, if the change was intended.

Please include a blink trybot on relanding this.

e61a957b2a Added constructor call on object in InstantiateObject method
I found after upgrading from 4.2.2 where apinatives.js still
existed to 4.4.56 where everything had been converted to C++ in
api-natives.cc, my constructors for ObjectTemplate instantiated objects
were no longer being called.  After investigation, I noticed in
apinatives.js that a new call would handle that, but there was no
corresponding constructor call in api-natives.cc (or anywhere else
along the chain of InstantiateObject), so I added a call to
Execution::Call to actually construct the object.  Forgive me if that
isn't the right place to add it (InitializeBody in objects-inl.h also
looked like a good place), or if there's a reason constructors are
not being called.

I also added myself to the AUTHORS file in this CL.

3badfdcd50 Re-write duplicated assertions
The modified assertions targeted the property descriptor for the
template object's first "cooked" value. The code immediately preceeding
these statements asserts these values.

Update the assertions to instead target the property descriptor for the
template object's first "raw" value (which are otherwise untested).

e8b9f2d7 introduced a different cast which broke building on Illumos.
Revert to previous behavior for V8_OS_SOLARIS only.

Found on SmartOS while building with gcc 4.9.0.

edit1: adding jochen to reviewers since he was assigned through the issue tracker and danno since he seems to do a fair amount of cross-platform work

edit2: removing BUG reference because I don't understand what LOG needs to contain (and it seems to link to chromium and not the v8 repo). Please edit commit message as appropriate.

531f7ab1d2 [turbofan] Better narrow the derived type for the right shift operation.
Currently the derived type of a right shift does not narrow the input
type based on the actual shift amount - well it does some narrowing
but more can be down. For patterns such as u32[i>>2], which is very
common is asm.js code, this limits the ability to later prove that an
index bounds check is unnecessary which can have a significant
performance impact.

Notes:
- All the added authors have signed the CLA.
- Updated 2 AUTHORS lines to match the e-mail addresses used for signing the CLA.
- In addition, checked that all authors in the AUTHORS file after this change
  have signed the CLA.
- Whenever it was possible to guess, based on the e-mail address, that the
  contribution was made under a corporate CLA, added the company and the
  wildcard instead of the individual.

Updating AUTHORS for companies who have signed CCLA.

Changes:
- Added wildcard rules for company e-mail addresses
- Removed individual e-mail addresses for contributors who are under a corporate
  CLLA (the copyright holder in this case is the company, not the individual
  authors). Domains affected by this change: intel.com, arm.com, codeaurora.org.

In addition, added a wildcard rule for Chromium (which was not previously
listed at all).

a4c072ed47 Fix a crash when generating forward jumps to labels at very high assembly offsets
The first jump to a specific label was marked as jump to absolute
position -4. This value was stored in the assembly as a branch to a
offset (-4 - (instruction offset + 8)). The offset is only 24 bit
long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow
the offset.

Fix by denoting the first jump to a label by storing the jump
instruction location as the target. This will result in offset of -8,
which of course always fits in the branch instruction.

53adf3b19c Add methods to allow resuming execution after calling TerminateExecution().
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.

* V8::CancelTerminateExecution() -- When execution is terminated via a call
  to V8::TerminateExecution(), this method can be called to clear the
  termination exception so that the engine can continue to be used.

* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
  exception, HasTerminated() will return true to indicate it is valid to
  call V8::ResumeExecution() if desired.

A test case is added to cctest/test-thread-termination.cc.
