Sintendo d877cfa4e2 JitArm64_Integer: Optimize subfic for zero
When the immediate value is zero, we can do a negation. On ARM64 the NEG
/NEGS instructions are just an alias for SUB/SUBS with a hardcoded WZR.

Before:
```
ldr    w22, [x29, #0x28]
mov    w21, #0x0                 ; =0
subs   w22, w21, w22
```

After:
```
ldr    w22, [x29, #0x28]
negs   w22, w22
```
