The observatory assets tarball would be different every time due to the
version string, which makes it compress to a different size. The size
changes would then move the program data around, making it much more
difficult to determine if dart builds of different revisions are
actually identical.
Google Analytics doesn't need to know the exact version numbers, it will
be fine to say they are bleeding edge builds of a particular version.
BUG=
R=whesse@google.com
Review URL: https://codereview.chromium.org/2540383003 .
The cause of the rebuilds was that in v 1.14, running `pub build` modifies pubspec.lock file (v 1.13 and below did not do this, bug filed #25688) resulting in unnecessary rebuilds.
- Remove two output build rules because they cause issues with Make.
- Write our own stamp file and use that instead of pubspec.lock.

Profiler improvements:
- Track Functions in profile and build Function based trie
- Associate code objects with functions
- Created cpu_profile.dart library
- Major speed improvements for disassembly view
- Fix truncation of disassembly comments
- Ability to get code object ticks from disassembly view
- Inlining mini-map in disassembly view.
- Remove a bunch of unused data from profile service response
- In some cases a caller PC that is better than the PC marker is inserted into the stack trace
- Inlined functions are expanded
- Ability to clear profile
- New flag '--keep_code' which keeps deoptimized code around for use by the profiler.
General fixes:
- Fix caching in service library
- Remove pubspec.yaml before running pub get

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.
