331cc8a278 Implement --omit, --raw_[context_]file=... for mksnapshot tool. 
These switches are analogous to --omit and --raw for js2c.py.
The goal it to allow embedders to externally load all (or generate) the V8 startup data.

There's a bit of gratuitous refactoring with the writing logic that helped me understand the code. Let me know if it's not an improvement.

6b4d4b7287 Reland "Track field types.". 
This is an initial step towards tracking the exact types instead of just
the representations of fields. It adds support to track up to one map of
heap object field values, eliminating various map checks on values
loaded from such fields, at the cost of making stores to such fields
slightly more expensive.

Issues with transitioning stores and fast object literals in Crankshaft
fixed.

ff953ac055 Make maps in monomorphic IC stubs weak. 
Maps in monomorphic Load, KeyedLoad, Store, KeyedStore, and CompareNil IC
stubs are treated as weak references by the marking visitor.

During generation of an IC stub with a weak map, the stub is appended to the
dependent code array of the map. When the map dies, all stubs in its dependent
code array are invalidated by setting embedded maps to undefined.

1d3f32ea79 Don't disable hash randomization option in predictable mode. 
We don't need it because
1) hash randomization uses random generator whose results depend on --random-seed option which is set in predictable mode.
2) disabling hash randomization triggers assert in snapshot mode.

8f170a66e7 Improve positions tracking inside the HGraphBuilder. 
Instead of tracking simple absolute offset from the start of the script like other places do, track a pair of (inlining id, offset from the start of inlined function).

This enables us to pinpoint with inlining path an instruction came from. Previously in multi-script environments we emitted positions that made very little sense because inside a single optimized function they would point to different scripts without a way to distinguish them.

Start dumping the source of every inlined function to make possible IR viewing tools with integrated source views as there was previously no way to acquire this information from IR dumps. We also dump source position at which each inlining occured.

Tracked positions are written into hydrogen.cfg as pos:<inlining-id>_<offset>.

Flag --emit-opt-code-positions is renamed by this change into --hydrogen-track-positions to better convey it's meaning.

In addition this change assigned global unique identifier to each optimization performed inside isolate. This allows to precisely match compilation artifacts (e.g. IR and disassembly) and deoptimizations.

e943623b12 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.

4e439deb0b 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.

adae3f77ec Allow redirecting disassembly and deoptimization traces into a file. 
This is controlled by two flags:

--redirect_code_traces
--redirect_code_traces_to=<filename>

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.

- Add a command-line flag --opt-code-positions to track source position information throughout optimized code.
- Add a subclass of the hydrogen graph builder to ensure that the source position is properly set on the graph builder for all generated hydrogen code.
- Overhaul handling of source positions in hydrogen to ensure they are passed through to generated code consistently and in most cases transparently.

52c421956a Make objects embedded in optimized code weak. 
This introduces a global weak hash table that maps objects embedded in
optimized code to dependent code lists. Using this table we can deoptimize
optimized code whenever a weak object embedded in the code dies.

10b45a5bc4 Less aggressive polling when concurrently compiling for OSR. 
Changes include:
- completed concurrent OSR tasks trigger a stack check interrupt.
- polling for completion is now guarded by a stack check.
- circular buffer for completed OSR tasks instead of list.

These flags are a no-op for a while, we kept them just because
Blink used to set them. After
https://src.chromium.org/viewvc/blink?revision=158187 they can be safely
removed.

It introduces static initializers for the new "MAYBE_BOOL" kind of
flags, which is a no-no for Chrome. This has to be done differently.
