*	Change sticky GC ergonomics to use GC throughput.	Mathieu Chartier	2014-03-27	1	-3/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The old sticky ergonomics used partial/full GC when the bytes until the footprint limit was < min free. This was suboptimal. The new sticky GC ergonomics do partial/full GC when the throughput of the current sticky GC iteration is <= mean throughput of the partial/full GC. Total GC time on FormulaEvaluationActions.EvaluateAndApplyChanges. Before: 26.4s After: 24.8s No benchmark score change measured. Bug: 8788501 Change-Id: I90000305e93fd492a8ef5a06ec9620d830eaf90d
*	Fix and optimize verify object.	Mathieu Chartier	2014-02-21	1	-0/+61
	VerifyObject no longer resides in heap. You can now enable VerifyObject for non-debug builds. VerifyStack is still slow, so it is now guarded by its own flag. Fixed the image writer to not use verification at places where verification fails due to invalid reads. Fixed RosAlloc to use SizeOf which doesn't call verify object. Added a flag paremeter to some of the mirror getters / setters to be able to selectively disable VerifyObject on certain calls. Optimized the GC to not verify each object multiple times during object scanning if verify object is enabled. Added 3 verification options: verify reads, verify this, and verify writes so that you can select how much verification you want for mirror getters and setters. Removed some useless DCHECKs which would slow debug builds without providing any benefits. TODO: RosAlloc verification doesn't currently work with verify objects.
