-----------
[Site Isolation] Don't use crashed processes in BrowsingContextGroup
https://bugs.webkit.org/show_bug.cgi?id=322868
rdar://186115818
Reviewed by Sihui Liu and Per Arne Vollan.
BrowsingContextGroup returns potentially terminated processes in both
sharedProcessForSite and
processForSite. Fix this by not handing back terminated processes.
