Simon Pilgrim c722b32596 [InstCombine] recognizeBSwapOrBitReverseIdiom - merge the regular/trunc+zext paths. NFCI. 
There doesn't seem to be any good reason for having a separate path for when we bswap/bitreverse at a smaller size than the destination size - so merge these to make the instruction generation a lot clearer.
