Add command line options

Add command line options
 - full-snapshot-after-run  (This option generates a full snapshot of an application after it is run with some sample input scenarios, this snapshot includes all the core libraries and other framework libraries and could be potentially tree-shaken to reduce the size)

- run-full-snapshot  (This option reads a full snapshot that was generated using the option above and runs it)

Example:
First generate the full application snapshot:

dart_no_snapshot --full-snapshot-after-run=script --package-root=..../packages/ ..../lib/_internal/compiler/implementation/dart2js.dart --categories=all ..../dummy_compiler_test.dart

Then run the full application snapshot generated above:
dart --run-full-snapshot=script ..../lib/_internal/compiler/implementation/dart2js.dart --categories=all ..../dummy_compiler_test.dart

LGTM.

Can the instructions for running --full_snapshot_after_run be saved as comment
in main.cc?

I would add a verb to this, as done with all other flags variables (e.g.,
is_noopt or use_noopt).
