- VECTOR_SHUFFLE of v4i32 / v4f32 with undef second vector always matches
...
PSHUFD. We can make permutes entries which point to the undef pointing
anything we want.
- Change some names to appease Chris.

- Use movaps to store 128-bit vector integers.
...
- Each scalar to vector v8i16 and v16i8 is a any_extend followed by a movd.

- Remove scalar to vector pseudo ops. They are just wrong.
...
- Handle FR32 to VR128:v4f32 and FR64 to VR128:v2f64 with aliases of MOVAPS
and MOVAPD. Mark them as move instructions and *hope* they will be deleted.
