Shift workarounds towards actual problem detection.

00f877e812 atomic.cpp: fix rare overload scenario
If slot allocation fails, increase reference counter in every slot.
This prevents search routine from "losing" some slots.

1e269751bf Temporarily disable memory locking if TSX is not used
It's a very heavy operation that could cause some problem under mutex lock.

0c7f9458c0 Fix thread pool resource management.
Make sure no tail call happens (change ret address to a trampoline).
Make sure thread handles don't leak if the pool is full.

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

cfda4d0ade atomic.cpp: optimize raw_notify() for unspecified pointer mode
Remove unnecessary optimization from cond_alloc().
Optimistic case was absolutely dominating anyway.
Although the whole function is a dirty hack.
Now scanning through all threads is faster.

e37df998e9 atomic.cpp: minor optimization
Silly MSVC emits unnecessary initialize-on-first-use code guards.
Didn't check other compiler. But workaround just works anyway.

c30cdfb3a7 atomic.cpp: merge more atomic variables for simplicity
Compress 16-bit ref counter and two 48+64 bit slot allocators.
This allowed to remove some weird unnecessary logic paths.
Adjust hashtable size to keep it the same.

7cd1e767be atomic.cpp: implement some atomic wait operations.
Instead of plain waiting while equal to some value,
it can be something like less, or greater, or even bitcount.
But it's a draft and untested. Hopefully doesn't break anything.

c047ab6147 atomic.cpp: waitable atomics got brutally rewritten
Hashtable increased and flatten, tree-alike extensions removed.
Some things simplified, so it can actually decrease perf a bit.
But most platforms shouldn't be affected.
Removed limit of 56 waiters per pointer.
Real limit now is about 65535.

d1ee7c651f Make memory locking optional (mlock, VirtualLock).
Fix desired locking operation (to fix "sudo" memory).
It was discovered that some systems have outdated configuration.
With too tight limit, it's almost impossible to lock anything in memory.

Debugger fixups (#9226)
Fix logic error in callstacks handling code, always set first to false after first iteration.
 Add explicit check for zero return addresses. Current code validity checks may not check for it properly when it sits on interrupt handler entry point (which may contain valid code).
 Do not allow 0x3FFF0 to be a back chain address because it needs space for LR save area, only 0x3FFE0 and below satisfy this criteria.
