Should we update __builtin_ia32_palignr?

[H.J. Lu]

Hi,

We currently define __builtin_ia32_palignr as

long long __builtin_ia32_palignr (long long, long long, int)

But it really should be

v1di __builtin_ia32_palignr (v1di, v1di, int)

Fix it won't affect sources which use intrinsics defined
in tmmintrin.h. But it may affect codes which use
__builtin_ia32_palignr directly. But I don't think there
are many users who use MMX version of gcc SSSE3
builtins directly. Should I submit a patch to change it?

Thanks.
