  Log Message:
  -----------
  [AArch64] Fix tryToConvertShuffleOfTbl2ToTbl4 with non-buildvector input operands. (#135961)

It looks like this code is only considering buildvector inputs,
expecting the inputs to have at least 16 operands. This adds a check to
make sure that is true.

Fixes #135950
