39623daef6 - Added support to turn "vector clear elements", e.g. pand V, <-1, -1, 0, -1> 
to a vector shuffle.
- VECTOR_SHUFFLE lowering change in preparation for more efficient codegen
of vector shuffle with zero (or any splat) vector.

44f1f09b4e Turn a VAND into a VECTOR_SHUFFLE is applicable. 
DAG combiner can turn a VAND V, <-1, 0, -1, -1>, i.e. vector clear elements,
into a vector shuffle with a zero vector. It only does so when TLI tells it
the xform is profitable.

c313c66a88 Added a virtual method isVectorClearMaskLegal to TLI. It is similar to 
isShuffleMaskLegal, used to determine if it makes sense to turn a
"vector clear" (e.g. pand V, <0, -1, 0, -1> to a shuffle of the vector and
a zero vector.

but i64 is not. If possible, change a i64 op to a f64 (e.g. load, constant)
and then cast it back.
