ac798ed144 [MachineOutliner] Annotation for outlined functions in AArch64
- Adding changes to support comments on outlined functions with outlining for the conditions through which it was outlined (e.g. Thunks, Tail calls)
- Adapts the emitFunctionHeader to print out a comment next to the header if the target specifies it based on information in MachineFunctionInfo
- Adds mir test for function annotiation

ea5a6285ae [AArch64] Prefer "mov" over "orr" to materialize constants.
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.)

e346f11594 [MachineOutliner] Don't save/restore LR for tail calls.
The cost computation assumes we do this correctly, but the actual
lowering was wrong.
