[AArch64] Prefer "mov" over "orr" to materialize constants.

[efriedma]

Summary

This is generally more readable due to the way the assembler aliases work.

(This causes a lot of test changes, but it's not really as scary as it looks at first glance. It's just mechanically changing a bunch of checks for orr to check for mov instead.)

[t.p.northover]

Looks fine to me.
