Bobby Holley	3836b7c35b	Bug 1258017 - Redesign and simplify rule tree GC. r=dbaron ... The basic idea here is as follows: * Rule nodes are reference-counted, but releasing them adds them to a linked list rather than freeing them. This allows for the reuse that motivated the original GC scheme. * We get rid of the marking, and instead rely on the reference count. * Sweeping no longer requires a complicated traversal. We just pop items off the free list until it's empty. When a child is destroyed, its parent may go onto the free list. * We remove special handling for the root node, and use a regular reference-counted edge from the style set. * The free list automatically asserts that it's empty (meaning all nodes have been freed) in its destructor, which runs when the style set is destroyed. * We get rid of the list of style context roots on the style set. We still need a count though, because of the HasCachedStyleData check.	2016-03-28 08:59:22 -07:00
