Ask legalize to promote all vector shuffles to be v16i8 instead of having to
...
handle all 4 PPC vector types. This simplifies the matching code and allows
us to eliminate a bunch of patterns. This also adds cases we were missing,
such as CodeGen/PowerPC/vec_splat.ll:splat_h.

* Add supprot for SCALAR_TO_VECTOR operations where the input needs to be
...
promoted/expanded (e.g. SCALAR_TO_VECTOR from i8/i16 on PPC).
* Add support for targets to request that VECTOR_SHUFFLE nodes be promoted
to a canonical type, for example, we only want v16i8 shuffles on PPC.
* Move isShuffleLegal out of TLI into Legalize.
* Teach isShuffleLegal to allow shuffles that need to be promoted.

int v = vec_any_out(*x, *y);
*x = (vector float)vec_cmpb(*x, *y);
*P = v;
}
we now generate:

When building a VVECTOR_SHUFFLE node from extract_element operations, make

sure to build it as SHUFFLE(X, undef, mask), not SHUFFLE(X, X, mask).
The later is not canonical form, and prevents the PPC splat pattern from
matching. For a particular splat, we go from generating this:

lis r11, ha16(LCPI1_0)

vperm v3, v2, v2, v3
