Skyrim SE: Hottest blocks
Skyrim SE's hottest blocks are really hot atomic loop blocks:
1- 6.83% of primary thread
```
6ffffd37ad33  89f8               mov     eax, edi  {0x1}
6ffffd37ad35  8706               xchg    dword [rsi], eax  {0x1}
6ffffd37ad37  85c0               test    eax, eax
6ffffd37ad39  7555               jne     0x6ffffd37ad90
```

2- 5.12% of primary thread
```
6ffffd4a8300  488d410c           lea     rax, [rcx+0xc]
6ffffd4a8304  f0ff08             lock dec dword [rax]
6ffffd4a8307  7407               je      0x6ffffd4a8310
```

3- 5.03% of primary thread
```
6ffffd4405f7  lea     rax, [rcx+0xc]
6ffffd4405fb  lock dec dword [rax]
6ffffd4405fe  jne     0x6ffffd44060d
```
lock dec at the very least can optimize away a mov+neg combination in to a mov. Looking at instcountci.

These three blocks are totaling 16.98% of CPU time on the primary thread on Cortex-A78AE. All coming from d3d11.dll in DXVK.
