  1. [InstCombine] Refactor matchFunnelShift to allow more pattern (NFC)

  1. [InstCombine] Convert or concat to fshl if opposite or concat exists 

    If there are two 'or' instructions concat variables in opposite order
and the first 'or' dominates the second one, the second 'or' can be
optimized to fshl to rotate shift first 'or'. This can eliminate an shl
and expose more optimization opportunity for bswap/bitreverse.
