With `-target aarch64-linux-gnu`, Clang 15 can compile the following code but Clang 16 cannot:
```c
#include <arm_neon.h>
poly128_t __attribute__((target("crypto")))
f(poly64_t a, poly64_t b)
{
return vmull_p64(a, b);
}
```
Clang 16 reports:
```
test.c:6:9: error: always_inline function 'vmull_p64' requires target feature 'aes', but would be inlined into function 'f' that is compiled without support for 'aes'
return vmull_p64(a, b);
^
```
Is this an intentional breaking change?
