JitArm64: Use LogicalImm in boolX

ARM64 has a special logical immediate encoding scheme, that can be used
with AND, ORR, and EOR. By taking advantage of this, we no longer need
to materialize the immediate value in a register, saving instructions
and/or reducing register pressure.

- orx

Before:
mov    w23, #0x1
orr    w23, w25, w23

After:
orr    w23, w25, #0x1

- andx

Before:
mov    w26, #-0x80000000
and    w27, w27, w26
sxtw   x24, w27

After:
and    w27, w27, #0x80000000
sxtw   x26, w27

- eqvx

Before:
mov    w23, #0x4

- norx

Before:
