arm64: ror+eor -> eor, ror

A pattern that can be found in `Marvin.Block`:
```cs
uint Block(uint p0, uint p1) => p0 ^ BitOperations.RotateLeft(p1, 23);
```
Current codegen:
```asm
    ror     w1, w1, #23
    eor     w0, w0, w1
```
Expected codegen:
```asm
    eor     w0, w0, w1, ror #23
```
