js-on-sx: lower array pad bail-out to 1M to kill remaining hang
The 2^32-1 threshold still allowed indices like 2147483648 to pad
billions of undefineds. Without sparse-array support there's no
semantic value in >1M padding; lowering the bail turns those tests
into fast assertion fails instead of timeouts.
built-ins/Array timeouts: 2 → 1. conformance.sh: 148/148.
