bors d1d79ae3ad Auto merge of #55701 - tromey:ice-fix, r=matthewjasper 
Fix emission of niche-filling discriminant values

Bug #55606 points out a regression introduced by #54004; namely that
an assertion can erroneously fire when a niche-filling discriminant
value is emitted.

This fixes the bug by removing the assertion, and furthermore by
arranging for the discriminant value to be masked according to the
size of the niche.  This makes handling the discriminant a bit simpler
for debuggers.

The test case is from Jonathan Turner.

Closes #55606
