OverflowError with large NTuple type

[garrison]

In the spirit of #11340, here's another regression:

julia> NTuple{20000,Int}
ERROR: OverflowError()

This seems to be intermittent; I can often get it to work a moment later until I go to an even larger value.

The OverflowError itself is intentional, added by #11330. However that change was not effective, since it just throws an exception at a random point and doesn't actually prevent you from constructing the type.

Also #11321 #11320

Closing as dup.
