Remove redundant code
Remove redundant code

The A_INDEXQ and A_LENGHTQ cases would already fall through to A_TAKE
containing precisely the same `if` (making the `if` redundant in case
the condition is true) and then falls through further to the `trap_it`
block (making the `goto` redundant in case the `if` condition is false).
