This fixes a bug where coverage for the inline script
<script>function foo() {}<script>
started to get deterministically reported as covered
after crrev.com/c/1771776, while before it, we most of
the time reported it as uncovered (depending on heap
order of SFIs). The correct result is to report `foo`
as uncovered as it is never called.
The problem arose from the fact that v8:9212 needed to
handle extra-wrappers around scripts correctly. Those
wrappers have the same source range as the wrapped
script and a call count of zero even if the wrapped
script is executed. To filter them out, we previously
determined nesting for identical source ranges by
ascending call count. However, in the script case above,
the script has call count one, while `foo` (which has
the same source range) has call count zero. In this
case, nesting is decreasing order of call counts.
This CL is a minimal change that sorts SFIs which are
top-level to the front, only then considers call counts
in descending order. This preserves the behavior that
node's extra wrappers are sorted to the front (and
then filtered out by existing logic), but also ensures
that for the example above, we report the script's
coverage before the coverage for `foo`.
