Bram Speeckaert 82f22cdfa1 JitArm64: cmp - Optimize a == -1 case
By explicitly handling this, we can avoid materializing -1 in a
register and generate more efficient code by taking advantage of -x ==
~x + 1.

Before:
0x12800015   mov    w21, #-0x1
0x93407eb9   sxtw   x25, w21
0x93407ef8   sxtw   x24, w23
0xcb180338   sub    x24, x25, x24

After:
0x2a3703f8   mvn    w24, w23
0x93407f18   sxtw   x24, w24
