When entering nterp, take a fast path for instance calls with 1 argument.

Such methods only take 'this' as an argument and we don't need to fetch
the shorty.

We can make this optimization when doing nterp->compiled as a follow-up,
by checking that the next instruction after the invoke is not
move-result(-wide).
