43952e18e2 Implement prefetch_write() and prefetch_exec() wrappers 
Do some refactoring to prefetch_read() in util/asm.hpp as well.
Make all these function constexpr because they are no-ops.

6d37bc62a5 CPU: remove cpu_counter from g_fxo 
Convert it to a namespace, simplify add/remove functions.
Don't add() threads just creates, they are trapped in check_state() anyway.
Don't add() threads which are leaving check_state() because stopped.

ab365fe494 Fixed thread pool a bit 
Use 128-bit allocator instead of queue.
When pool is full (128), threads just terminate as before.

557f0c5a8a atomic.cpp: remove load() from notify functions 
Only compare masks for overlap for second overload (with mask provided).
Explicit "new value" can be provided in new 3-arg overloads.
Also rename atomic_storage_futex -> atomic_wait_engine.

0da24f21d6 CPU: improve cpu_thread::suspend_all for cache efficiency (TSX) 
Add prefetch hint list parameter.
Workloads may be executed by another thread on another CPU core.
It means they may benefit from directly prefetching the data as hinted.
Also implement mov_rdata_nt, for "streaming" data from such workloads.

6806e3d5c7 atomic.cpp: implement notify callback 
Notification can be very heavy, especially if we need to wake many threads.
Callback is set for cpu_thread in order to set wait flag accordingly.
