70761a4ef0 atomic.cpp: fix notification bug from few commits before 
Make sure forced notification ignores mask comparison.
Also fix masks provided by smaller types to correct ones.

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.

350b704cd7 atomic.cpp: combine two atomics (ref ctr and wait ptr) 
Should fit into cache line perfectly.
Also makes ptr check more robust.

ad013d59f4 atomic.cpp: don't load actual memory on empty mask 
It's not an optimization. It just allows some tricks safely.

d391133524 atomic.cpp: minor notification improvement 
Check mask before locking the reference.
Can help to not bother non-eligible waiters.

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It was discovered that some systems have outdated configuration.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.

b68bdafadc vm: refactor vm::range_lock again 
Move bits to the highest, set RWX order.
Use only one reserved value (W = locked).
Assume lock size 128 for range_locked.
Add new "Size" template argument that replaces normal argument.

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.
