Performance of command line dart with new front-end running dart programs is acceptable

@mhausner @a-siva @sigmundch Please populate this issue with performance targets for specific benchmarks.

Friendly ping. Please fill in targets here. @johnmccutchan

$ time dart hw.dart
hello world

real	0m0.139s
user	0m0.130s
sys	0m0.035s

More importantly, larger apps should perform equally well:

$ time out/ReleaseX64/dart-sdk/bin/dart2js ~/examples/hello.dart 

real	0m0.553s
user	0m0.506s
sys	0m0.233s

@fsc8000 I agree your number is better.

Here is dart2js being run from source on a Z840.

$ time ./out/ReleaseX64/dart pkg/compiler/lib/src/dart2js.dart ~/hw.dart 

real	0m2.518s
user	0m3.010s
sys	0m0.463s

I am closing this issue as not actionable. We are in progress of switching irrespective of current performance characteristics - which means we deemed the performance acceptable.
