Clang allows programs like this, with a use of a 3xi64 vector type:
```
typedef long vec_long_24 __attribute__((__vector_size__(24)));
vec_long_24 global_long_24;
extern void passCallee_long_24(vec_long_24 x);
void loadAndPass_long_24(void) {
passCallee_long_24(global_long_24);
}
```
GCC however reports `"error: number of vector components 3 not a power of two"`, per its documentation.
Is this intentional or should clang as well report the error?
