[PATCH] D59720: [AArch64] Prefer "mov" over "orr" to materialize constants.

Herald added a project: LLVM.

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.)
