Benjamin Kramer bb81d9d5fa SDAG: Legalize vector BSWAP into a shuffle if the shuffle is legal but the bswap not.
- On ARM/ARM64 we get a vrev because the shuffle matching code is really smart. We still unroll anything that's not v4i32 though.
- On X86 we get a pshufb with SSSE3. Required more cleverness in isShuffleMaskLegal.
- On PPC we get a vperm for v8i16 and v4i32. v2i64 is unrolled.
