      [heap] Start making ReadOnlySpace Pages relocatable · 7485b129
      Dan Elphick authored 
      Adds Page::MakeHeaderRelocatable that clears pointers to objects
outside the space. In this case relocatable means the entire page
heading is position independent in memory, meaning it could be saved to
disk and reloaded at a different memory location in a new process
without there being any invalid pointers.

Currently this only affects mutex_, locate_tracker_ and reservation_.

Additionally makes VerifyHeap work when there's no mutex in a Page.

This is just a stepping stone to making the Pages headers relocatable
since heap_ and owner_ still point out of the Page.

Also removes the empty ReadOnlySpace destructor.

      Import ConditionVariable class. · 281de965
      bmeurer@chromium.org authored 
      Condition variables are synchronization primitives that can be used
to block one or more threads while waiting for condition to become
true.

Right now we have only semaphores, mutexes and atomic operations for
synchronization, which results in quite complex solutions where an
implementation using condition variables and mutexes would be straight
forward.

There's also a performance benefit to condition variables and mutexes
vs semaphores, especially on Windows, where semaphores are kernel
objects, while mutexes are implemented as fast critical sections,
it CAN be beneficial performance-wise to use condition variables
instead of semaphores.
