    Following up the discussion on the AArch64 Sync call (2024-01-09):

While debugging OpenMP (`ompt/synchronization/master.c`), I noticed this:

``` ce8:   91364000        add     x0, x0, #0xd90
 cec: 97ffff19        bl      950 <__kmpc_end_master@plt>
 cf0:   14000001 b       cf4 <main.omp_outlined+0xd4>
 cf4:   d503201f        nop
 cf8: 14000001        b       cfc <main.omp_outlined+0xdc>
 cfc:   d0000088 adrp    x8, 12000 <__gmon_start__@Base>
 d00:   f9404d08        ldr x8, [x8, #152]

```
I'd expect the `nop` to be followed by the `adrp`. Instead, there is an unconditional branch to the `adrp`.

I've seen this pattern in other parts of the code as well, but this is the example I had at hand. I can try to create a smaller reproducer, if necessary.
