However, this can never happen, because the 'case' values in each place are 0x0nn or 0x1nn and the switch will have directed the b1 == (2, 3) cases to the default already. This check was added in commit c045af25a52e9 in 2010; the added code was unnecessary then as well, and was apparently intended only to ensure that we never accidentally ended up indexing off the end of an sse_op_table with only 2 entries as a result of future bugs in the decode logic. Change the checks to assert() instead, and make sure they're always immediately before the array access they are protecting.
