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
