Add a global flag indicating that we're in the servo traversal. v3

Details | Diff | Splinter Review
There are various situations where we avoid caching things or otherwise take different behavior to prevent race conditions during the parallel servo traversal. Right now we check NS_IsMainThread, but that's overly-general and incurs a TLS lookup. Instead, we should just set a global flag when we begin the traversal (since the main thread is blocked), and clear it when the traversal is complete.

Comment on attachment 8833071 [details] [diff] [review] Add a global flag indicating that we're in the servo traversal. v3 I guess this works for now, though how this plays with quantum DOM is less clear to me...

That is another bridge to cross at a later point. :-)
