[FEATURE ember-routing-auto-location] Enable by default.

This feature was given a 'Go' in the core team meeting today
(2014-01-31). As such it should be enabled by default for all future
canary builds. This will help ensure that it has more review prior to
shipping the 1.5.0 beta series.

Don't deoptimize every Ember.run

TryCatchStatements are currently non-optimizable statements in v8 (and likely other run times). Additionally, methods containing try/catch statements are not inlineable

Although Ember.run's shouldn't be in a tight loop, we should incur the deopt penalty if we don't even use Ember.onerror
