With this patch, the following testcase gets a warning for "synthetic
vector returned by reference" for -maltivec -mabi=no-altivec.  It's not
a real call, just a call to an AltiVec builtin, so the warning isn't
needed.

#include <altivec.h>
extern vector int a1, a2, a3;
void
foo ()
{
  a3 = vec_add (a1, a2);
}

This causes lots of bogus test failures.
