\\tfmov\\td[0-9]+, x[0-9]+ 2

What the trunk produces is better:
```
f_s16:
.LFB3886:
        .cfi_startproc
        fmov    s31, w0
        fmov    s0, w1
```

vs 14:
```
f_s16:
.LFB3916:
        .cfi_startproc
        sxth    w0, w0
        sxth    w1, w1
        fmov    d31, x0
        fmov    d0, x1
```

So this one is just a testsuite change. I will submit that later today.

I have not looked into the others.
