Currently, for the ppc64--gnu and aarch64 ABIs, we recognize:
typedef __attribute__((__ext_vector_type__(3))) float v3f32;
typedef __attribute__((__ext_vector_type__(16))) char v16i8;
struct HFA {
v3f32 a;
v16i8 b;
};
as an HFA. Since the first type encountered is used as the base type,
we pass the HFA as:
[2 x <3 x float>]
Which leads to incorrect IR (relying on padding values) when the
second field is used.
Instead, explicitly widen the vector (after size rounding) in
isHomogeneousAggregate.
