This can be done, we can deprecate attribute in favour of
__attribute__ and add new enums for shortcut paths to access the
internal attributes.

One way could be as above, alternatively if name clashing is a
problem, then we can always prefix with GNU_

---
enum GNU_forceinline = __attribute__("forceinline");
/* etc... */

auto GNU_target(A...)(A args)
    if(A.length > 0 && is(A[0] == string))
{
    return __attribute__("target", args);
}
---

Then in user code:

---
import gcc.attribute;

@GNU_forceinline int foobar();
@GNU_target("sse3") float4 mySSE3Func();
---
