The new config is now used for perf measurements. The old
ones are deleted to avoid redundancy.

This also ports https://codereview.chromium.org/754523004 to the new config file.

b27431d52f Cleanup: Remove NativesCollection<.>::*Raw* methods. 
These methods for used for compressed libraries, where GetSource* functions
contained the compressed sources and [GS]etRawSource* the uncompressed
sources. This is dead code since the API no longer supports compression.

(If you need/want compressed sources, use the external startup data and
 compress/uncompress on the Embedder's side.)

1364ea7c77 Make JSTests ready for Android measurements. 
This adds a common perf configuration for JSTests including
Classes, Collections, Iterators and Strings. This allows
the android test runner to handle subdirectories correctly
and to share the base.js resource in the parent directory.

The new json config has added resources configs for the
Android runner.

The perf runner's relative paths on the device are fixed as
well. Resources are only pushed on the configuration node
where they are specified. They are pushed to a dir on the
device that follows the same directory structure as on the
host. The binary is executed in the benchmark folder on the
device like on the host to allow relative path file
loading.

02cb54e3cc Make test-parsing faster: don't run parsing tests with all experimental flag combinations. 
Instead, make it possible for indifidual tests to pass "always true flags" which
are not part of the varying flag set.

The downside is that if an experimental flag changes parsing of some of the
unrelated code snippets, it's noticed later (only after the flag is turned on by
default). But this is a reasonable trade off for faster tests.

Additional fix: Some tests (ErrorsFutureStrictReservedWords) were using
always_flags incorrectly (running two different tests with different
always_flags basically iterates over every flag combination anyway - most of
them twice).

d3c217674f Make the ParserSync test faster (and re-enable it). 
Most of the run time came from testing with all possible flag combinations. None
of the flags passed affect the test, and there are specialized tests for testing
the features behind the flags; no need to slow down the generic test.

With these changes, run time for debug build goes from 186 s to 0.5 s.

In addition, fixed some missing commas between the test cases.

marked for optimization before it's ever been compiled by fullcode.
This can lead to the situation where a function doesn't have optimization
disabled until we try to compile it optimized.

Basically, the assert should just handle this case more gracefully.

6ac4de87a8 harmony-scoping: make assignment to 'const' a late error. 
Per TC39 Nov 2014 decision.

This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

fd13969ef0 Disable ParserSync test for now, it takes waaaaay too long. 
Running this in x64.release mode on a powerful HP620 takes 4 seconds,
this is at least 2 orders of magnitude too slow and leads to tons of
false positives on our build bots due to timeouts. As it is, the
cost-benefit ratio is far too low.

The whole approach needs to be changed: Instead of trying to exhaust
some search space in unit tests, this should be turned into a fuzzing
test where only a small but random number of things are tested. The
exhaustive approach can be done separately, but definitely not in the
unit tests.

test has since been moved to unittests/Thread.SelfJoin. Move the
suppression to unittests.status.

unittests/ThreadLocalStorageTest.DoTest fails on older Android devices
as it assumes the availability of more TLS slots than many devices
implement. Test a smaller number of slots (32) on Android. Remove old
suppression of test-platform-tls/FastTLS (which no longer exists).

with shared mappings. Check for 's' instead of '-'.

fbcfce69aa Conditional flags for tests - set JS stack size for simulators. 
There are separated JS and C stacks on simulators so for some stack
extensive tests (like mozilla/js1_5/extensions/regress-355497) might
cause a C stack overflow and that overflow is not caught by V8. It is
not an issue on real HW. Increasing the C stack also solves the problem
but we have already FLAG_sim_stack_size flag to control the JS stack
size.

This patch makes it possible to add flags to tests conditionally in
.status files.

c3af691e72 [turbofan] Remove int32 narrowing during typed lowering. 
With Int32Add we lose the int/uint distinction, so later, in simplified lowering we can make a wrong decision. E.g., see the attached test case, where we lower NumberAdd -> Int32Add because inputs are Uint32, but during simplified lowering we change the inputs to Int32, so we get a wrong result.

Simplified lowering will lower the NumberAdd operations anyway, so we should lose performance.

There's no need to apply the 0x1f mask to right hand sides of shifts if
the input is already in range [0,31].

aa6815c79a Classes: Add support for arguments in default constructor 
This is currently done by generating a default constructor that looks
like this:

  constructor() {
    %DefaultConstructorSuperCall();
  }

The a runtime function implements the logic which is pretty similar to
Runtime_Apply except that it uses the [[Prototype]] of the current
function.

This is the second try. The first failed because the test was using a
array that was too large for Function.prototype.apply.

Revert "Revert "Classes: Add support for arguments in default constructor""

This reverts commit 43aa7e541df56a132608b8b4217e9da84575e4f8.

3b3929fdc7 Reland "Avoid some unnecessary fast-properties map creations." 
This relands commit ea74f0f85a.

The revert was due to failures in cctest/test-heap/ReleaseOverReservedPages,
caused by apparent changes to memory layout and fragmentation of the
first page. Eliminating a situation in messages.js where this CL has had
an effect on map transitions seems to solve the issue.
