Nekotekina 4966f6de73 vm: improve range_lock and shareable cache (Non-TSX) 
Allocate "personal" range lock variable for each spu_thread.
Switch from reservation_lock to range lock for all stores.
Detect actual memory mirrors in shareable cache setup logic.

eladash 730e9cde84 sys_rsx: Improve allocations and error checks 
* allow sys_rsx_device_map to be called twice: in this case the DEVICE address retrived from the previous call returned
* Add ENOMEM checks for sys_rsx_memory_allocate and sys_rsx_context_allocate
* add EINVAL check for sys_rsx_context_allocate if memory handle is not found
* Separate sys_rsx_device_map allocation from sys_rsx_context_allocate's
* Implement sys_rsx_memory_free; used by cellGcmInit upon failure
* Added context_id checks
* Throw if sys_rsx_context_allocate was called twice.
