Prior to v8, this case is UNDEFINED. With v8, this is CONSTRAINED UNPREDICTABLE and may either raise an exception or force align the PC. We choose to raise an exception because we have the infrastructure, it makes the generated code for gen_bx simpler, and it has the possibility of catching more guest bugs.

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.
