I've tried the first step - putting the attributes that require type to
TYPE_ATTRIBUTES rather than DECL_ATTRIBUTES, see below.
Unfortunately tsubst doesn't call apply_late_template_attributes in that case

We also need to make sure the target specific attribute __altivec__ (powerPC)
and __spu_vector__ (SPU) works correctly just as vector_size works.

Hmm, for some reason __spu_vector__ works correctly for my testcase but not
__altivec__; I have not looked into why though.

See http://gcc.gnu.org/ml/gcc-patches/2008-04/msg00177.html
for details.
I guess before moving further along with this, attributes for parameter packs
should be decided upon. Do we want to allow them at all? What

Actually, to clarify #c10, attributes on parameter packs just make things
harder on the compiler side, but even in C++98 the same issue is present:
#define vector __attribute__((__vector_size__ (16)))

I think this shows that vector_size attribute can't be a late template
attribute whenever processing_template_decl, it can be only a late template
attribute if the decl is actually type or value dependent.
So I
--- Comment #6 from pinskia at gcc dot gnu dot org 2008-03-31 00:16 ---
So what is happening is we are not applying the attribute while doing overload
resolution so we reject the template function then.

That being said, I think fn_type_unification should apply the attributes but I
don't know/understand the template part of the C++ front-end.

This is caused by the delaying of vector_size attribute inside templates.
