  Log Message:
  -----------
  [VectorCombine] foldSelectShuffle - early-out cases where the max vector register width isn't large enough (#157430)

Technically this could happen with vector units that can't handle all legal scalar widths - but its good enough to use a generic crash test without a suitable target

Fixes #157335
