[InstCombine] matchBSwapOrBitReverse - remove pattern matching early-out. NFCI.
recognizeBSwapOrBitReverseIdiom + collectBitParts have pattern matching to bail out early if a bswap/bitreverse pattern isn't possible - we should be able to rely on this instead without any notable change in compile time.
This is part of a cleanup towards letting matchBSwapOrBitReverse /recognizeBSwapOrBitReverseIdiom use 'root' instructions that aren't ORs (FSHL/FSHRs in particular which can be prematurely created).
