This commit reverts a8d9dbf that introduced a code size regression (16kb gzipped, 63kb minified) in Dart.
Effect on the hello world app:
gzipped: 105kb -> 89kb
minified: 370kb -> 317kb
BREAKING CHANGE:
- This is very unlikely to be breaking, but I'm still marking just in case. The only change to the user should be that dev mode is driven by Dart's checked mode, like it was in the past.
