    Add support for byte endian swapping for Word 16/32/64.
    
      * Exposes bSwap{,16,32,64}# primops
      * Add a new machop: MO_BSwap
      * Use a Stg implementation (hs_bswap{16,32,64}) for other implementation
        in NCG.
      * Generate bswap in X86 NCG for 32 and 64 bits, and for 16 bits, bswap+shr
        instead of using xchg.
      * Generate llvm.bswap intrinsics in llvm codegen.
