Bug 807480 - Add Rooted<T> roots to PerThread state. r=luke Currently there are a number of global fields in JSRuntime* which are basically tracking per-thread state. This makes sense on the current trunk since there is only ever a single thread associated with a runtime, but as Parallel JS (nee Rivertrail) starts to land this assumption no longer holds. This patch makes a struct, currently called |JS::PerThreadData|, that stores per-thread data from the runtime. There is one instance of this struct embedded in "Runtime" itself (the field |mainThread|). For now I have only migrated the debug GC fields into |PerThread|, those are the ones causing me immediate pain. Eventually more fields will want to move into there. The eventual goal is to distinguish thread-safe code, which will take as argument a |JS::PerThread*|, from non-thread-safe code, which will take a |JSRuntime*| or |JSContext*|.

If you have a question about developing Mozilla, and can't find the solution
on http://developer.mozilla.org, you can try asking your question in a
mozilla.* Usenet group, or on IRC at irc.mozilla.org. [The Mozilla news groups
are accessible on Google Groups, or news.mozilla.org with a NNTP reader.]

You can download nightly development builds from the Mozilla FTP server.
Keep in mind that nightly builds, which are used by Mozilla developers for
testing, may be buggy. Firefox nightlies, for example, can be found at:
