b4470ea4cf Reland "[bigint] Fix early-return in asIntN" 
For "top digit" (of the result) comparison to be applicable, we must
also check that there are no further digits in the source.

The included regression test flushes out another bug in "TruncateToNBits",
so that gets fixed here too (in contrast to the first landing attempt).

This reverts commit cb9e7af4e5.
