* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")
* Multi-thread shader compilation
This offers a huge improvement in startup performance. With around 13,000 shaders we go from ~1:30 to under 10 seconds. It looks like this was the original intention of the author given the outer scope recompile variable.

Disable features still unimplemented by lavapipe when using it:
- samplerAnisotropy
- shaderStorageBufferArrayDynamicIndexing
- wideLines
as of mesa 21.1.0-dev (aea36ee05e9, 2020-02-10)
- Avoids a silly situation where a texture is discarded and an identical copy created immediately afterward.
Unfortunately allocating memory blocks is really slow so avoid it as much as possible.
* Set the ground for RSX modes of register editor and insttruction editor, do not use shared ptrs directly.
* Make register editor and instruction editor modeless to allow to copypaste values from thread context etc in the background.
- The driver seems to cache page mapping as long as allocation has not been removed
- This is undesirable as we cannot stop the emulator to remove stale allocations every time a page is unmapped
- It is not possible to emulate passthrough memory cleanly, and we don't need to
A stupid race condition appears when trying to synchronize DMA blocks with memory inheritance.
Since the usage pattern is to acquire a range and then load or write+flush, this new data is going to be..
overwritten by the commandbuffer execution sequence later. Acquiring a scratch buffer to hold CPU content during the transition is not worth the effort..
as the data will be destroyed anyway during the transfer process immediately afterwards.
Fixes data corruption when moving data around using the emulated DMA passthrough
