Evgeniy Stepanov bb91e02efd [msan] Make origin tracking fork-safe. 
Chained origins make plain memory stores async-signal-unsafe.
We already disable it inside signal handlers.
This change grabs all origin-related locks before fork() and releases
them after fork() to avoid a deadlock in the child process.
