[AArch64] Allow forcing unrolling of small loops (#167488) 
- Introduce the -aarch64-force-unroll-threshold option; when a loop’s
cost is below this value we set UP.Force = true (default 0 keeps current
behaviour)
- Add an AArch64 loop-unroll regression test that runs once at the
default threshold and once with the flag raised, confirming forced
unrolling
