Simon Pilgrim 3aa93f690b [InstCombine] recognizeBSwapOrBitReverseIdiom - support for 'partial' bswap patterns (PR47191) (Reapplied) ...

If we're bswap'ing some bytes and zero'ing the remainder we can perform this as a bswap+mask which helps us match 'partial' bswaps as a first step towards folding into a more complex bswap pattern.

Reapplied with early-out if recognizeBSwapOrBitReverseIdiom collects a source wider than the result type.
