Support invalidation sets for negated selectors.

Support invalidation sets for negated selectors.

Add invalidation set features to invalidation sets for negated classes, ids,
etc. But still treat negated features as universal selectors and trigger
subtree recalc.

Example selector -> invalidation set mappings:

":not(.a)"    -> ".a {}"
":not(.a) .b" -> ".b {}, .a { .b }"
".a :not(.b)"  -> ".a { * }, .b {}"
".a .b:not(.c)" -> ".a { .b }, .b {}, .c {}"

lgtm, this seems pretty reasonable. We can add more complexity when we find that
:not() is common.
