[PATCH][AArch64] Custom lower concat_vector patterns with v4i16, v4i32, v8i8, v8i16, v16i8 types.

[Chad Rosier]

All,
The attached patch custom lowers concat_vector patterns with v4i16, v4i32,
v8i8, v8i16, v16i8 types that have the same operand of type v1* using the
DUP instruction.  In the case of a constant operand the VDUP, rather than
VDUPLANE, is used because it avoids an INS instruction.
