asiva 5399dbf6f6 [VM/dartdev] Switch dartdev to use an AOT runtime. 
- split the Dart CLI tool out of the VM into it's own embedder which
  runs in AOT mode. The pure Dart VM executable is called 'dartvm' and
  has no Dart CLI functionality in it
- the Dart CLI executable parses the CLI commands and invokes the rest
  of the AOT tools in the same process, for the 'run' and 'test'
  commands it execs a process which runs 'dartvm' to run
- 'dart hello.dart' execs the 'dartvm' process and runs 'hello.dart'
- the Dart CLI is not generated for ia32 as we are not shipping a
  Dart SDK for ia32 anymore (support to execute the 'dartvm' for ia32
  architecture is retained)
- the Dart CLI tool is not built in the internal Dart SDK builds

TEST=ci

Some performance improvement numbers
'dart format pkg/dartdev' goes from 1.17 secs to 0.22 secs
'dart doc pkg/dartdev' goes from 100.2 secs to 66.6 secs
'dart fix pkg/dartdev' goes from 19.3 secs to 14.5 secs
