koda@google.com 5d9e207c44 Double-align Zone allocations to fix MIPS issue. 
Also ensure initial buffer is aligned.

~2% increase in total allocated zone memory on compile-heavy benchmarks.
No significant impact on speed for either ia32 or arm.

koda@google.com 01dfb15825 Grow allocation in Zone::Realloc when possible. 
Typical success rate is 30-40% of calls to Realloc, which is used by GrowableArray.

Typical total zone memory savings are ~3%.

koda@google.com 98e2fafbf2 Rank most retaining instances for each class. 
Keep a heap snapshot (object graph) in the isolate.
On request from a class view, show 10 most retaining instances.

Currently, a new snapshot is fetched every time a ranking is requested.
In the future, we will want more fine-grained management of snapshots,
with its own dedicated view/console.

johnmccutchan@google.com 9d6ac72b46 1) Remove prebuilt Observatory sources 
2) Move observatory from runtime/bin/vmservice/observatory to runtime/observatory

3) Add two tools scripts:
- tools/run_pub.py (runs pub before SDK is built)
- tools/obs_tool.py (helper for get, build, and deploy stages)

4) Build Observatory with runtime:
- pub get --offline
- pub build
- deploy

5) Build artifacts are now in standard output directory, for example, out/DebugIA32/observatory.

6) Add a new 'dart_boostrap' host target (no snapshot, no observatory) that can be used as the Dart executable to run pub when building Observatory. This is behind a build.py flag --use-bootstrap-for-observatory because:

- It is only necessary on older Linux distributions that are incompatible with the prebuilt Dart testing executable.
- running pub build with the boostrap Debug build is significantly slower.

7) Detect if the prebuilt executable doesn't work and automatically switch to the 'dart_bootstrap' executable. Also, warn the user and provide a Wiki link with more information.

koda@google.com 0b85873fc8 Deletion barrier preparation: validate overwritten references. 
With the upcoming deletion barrier, every update of a pointer field must know whether the previous value was a valid pointer.

Currently, we always use StorePointer/StoreSmi, both for initialization and updates.

Initialization, and thus the potential for overwriting garbage values, appears in three places:
1. Object::Allocate/Foo::New.
2. Creating isolate from full snapshot.
3. Allocation in generated code.

Case 1 already null-initializes all underlying memory.
Case 2 is addressed by this CL by exploiting that:
i) fresh pages are zero-filled by OS, and
ii) freelist headers use only even values.
Case 3 is remains a TODO for future CLs.

(An alternative solution for case 2 would have been to add an init_foo method for every set_foo called.)

hausner@google.com 74694f5a90 Interrupt isolates immediately 
After requesting the interrupt, send a null message to the isolate
to ensure the isolate runs and detects the interrupt request immediately.

hausner@google.com ab3af6ec00 Introduce is_debuggable state bit on function objects 
Simplify debugger logic. Any function can be marked as
non-debuggable when is is created. The debugger no longer
needs a heuristic which functions are debuggable.
Mostly used for synthetic, generated functions that
have no source code, e.g. async code, implicit getters and
setters, implicit constructors, forwarding constructors,
dispatcher functions.

fschneider@google.com 009eb5d33c Move ConstantPropagator from flow_graph_optimizer.cc/.h into separate files. 
flow_graph_optimizer.cc is becoming unnecessarily large, so
I'm  moving self-contained optimization passes into
separate files.

In a separate CL I'll also move load/store optimization into
separate files.
