Vector Splat Immediate Signed Integer

`vec_splat_s8(arg1) vec_splat_s16(arg1) vec_splat_s32(arg1) vec_splat_u8(arg1) vec_splat_u16(arg1) vec_splat_u32(arg1)`

Each element of the result is set to the value obtained by sign-extending arg1. This permits values ranging from -16 to +15 only for the signed results. The unsigned results are obtained by casting the signed result to an unsigned value. Thus, the unsigned char result will lie in the range 0-15 or 240-255; the unsigned short result will lie in the range 0-15 or 65520-65535; and the unsigned long result will lie in the range 0-15 or 4294967280 to 4294967295.
See Example 4 of Highlights for a diagram of this operation.
