Add dump_record to make inspecting before/after SkRecordOptimize easy.

E.g.
dump_record -r http___groupcloned_com_test_plain_list_animation_simple_html_layer_109.skp

 0 Save
 1 	DrawRect
 2 	DrawRect
 3 	DrawRect
 4 	DrawRect
 5 	Save
 6 		ClipRect
 7 	Restore
 8 	Save
 9 		ClipRect
10 	Restore
11 Restore

dump_record -O -r http___groupcloned_com_test_plain_list_animation_simple_html_layer_109.skp
 0 Save
 1 	DrawRect
 2 	DrawRect
 3 	DrawRect
 4 	DrawRect
 5 	NoOp
 6 	NoOp
 7 	NoOp
 8 	NoOp
 9 	NoOp
10 	NoOp
11 Restore

(Reitveld sadly eats my kickass indentation.)
