Harmony promises
Based on prototype at
https://github.com/rossberg-chromium/js-promise
which informed the latest spec draft version at
https://github.com/domenic/promises-unwrapping/blob/master/README.md
Activated by --harmony-promises.
Feature complete with respect to the draft spec, plus the addition of .when and .deferred methods. Final naming and other possible deviations from the current draft will hopefully be resolved soon after the next TC39 meeting.
This CL also generalises the Object.observe delivery loop into a simplistic microtask loop. Currently, all observer events are delivered before invoking any promise handler in a single fixpoint iteration. It's not clear yet what the final semantics is supposed to be (should there be a global event ordering?), but it will probably require a more thorough event loop abstraction inside V8 once we get there.

The goal is to discover the appropriate heap space for objects created in full
code. By the time we optimize the code, we'll be able to decide on new or old
space based on the number of surviving objects after one or more gcs.
The mechanism is a "memento" placed behind objects in the heap. It's currently
done for array and object literals, with plans to use mementos for constructed
objects as well (in a later CL).
The feature is behind the flag allocation_site_pretenuring, currently off.

Original commit message:
A performance regression in array literal creation was caused by refactoring that eliminated a special fast case for shallow arrays. At the same time the general case got a bit slower. This CL restores most of the performance without coding the special fast case. The virtual dispatching is unnecessary because we know what we want to do at compile time. A flag was added to Runtime::CreateArrayLiteral. The flags delivers information about shallowness but also whether or not allocation mementos should be created. This is useful for crankshafted code.

A performance regression in array literal creation was caused by refactoring that eliminated a special fast case for shallow arrays. At the same time the general case got a bit slower. This CL restores most of the performance without coding the special fast case. The virtual dispatching is unnecessary because we know what we want to do at compile time. A flag was added to Runtime::CreateArrayLiteral. The flags delivers information about shallowness but also whether or not allocation mementos should be created. This is useful for crankshafted code.

Support for the Linux 'perf report' and 'perf annotate' tools.
In this change, the support comes in two flavours:
--perf_jit_prof - outputs the files in a new perf format that only works with a
patched perf tool (patch obtained from Stephane Eranian). Both 'perf report' and
'perf annotate' are supported (the file format also contains the machine code).
--perf_basic_prof - outputs the files in a format that the existing perf tool
can consume. Only 'perf report' is supported.
In both cases, we have to disable code compaction because the perf tool does not
understand code relocation. (We are told that code relocation should be
supported soon.)
Usage:
perf record -g d8 --perf_jit_prof --no_compact_code_space my.js
perf report
The change itself is straightforward - we simply listen to code events and
write an entry to a log file for every new piece of code.
I am not yet sure whether we should keep both versions or just one (and which
one). My hope is the reviewers can help here.

MIPS: Fix and simplify code aging.
This commit fixes a lot of test failures that we saw earlier in the buildbots (http://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20mips%20-%20sim/builds/3034/steps/Check/logs/stdio).
In some very rare cases the code age stub address can be 0xXXXX0000 and in this case the li maco instruction emits only 1 instruction (instead of the expected 2). Thus the code age sequence will be 6 instructions long instead of 7, which breaks the code aging feature. This change makes sure that li always emits 2 instructions and it also simplifies the code aging sequence.
Also fixes a small mistake in the simulator at the jalr instruction.

For 31-bit smis, we don't need to explicitly check whether the
combined string length exceeds the max supported string length,
since the value must be converted to a smi at some point (i.e.
when it is stored into the string length field of the resulting
string), which will emit an overflow check.

Use %_IsSmi instead of %MaxSmi.
ToPositiveInteger already makes sure that if l can be represented as a
smi, it will be represented as a smi. This way we can avoid doing a
runtime call to retrieve a constant.

Implement Math.random() purely in JavaScript.
This removes tons of architecture-specific code and makes it easy to
experiment with other pseudo-RNG algorithms. The crankshafted code is
extremely good, keeping all things unboxed and doing only minimal
checks, so it is basically equivalent to the handwritten code.
When benchmarks are run without parallel recompilation, we get a few
percent regression on SunSpider's string-validate-input and
string-base64, but these benchmarks run so fast that the overall
SunSpider score is hardly affected and within the usual jitter. Note
that these benchmarks actually run even faster when we don't
crankshaft at all on the main thread (the regression is not caused by
bad code, it is caused by Crankshaft needing a few hundred microsecond
for compilation of a trivial function). Luckily, when parallel
recompilation is enabled, i.e. in the browser, we see no regression at
all!
