[ValueTracking] peek through extends in haveNoCommonBitsSet (2nd try)
The 1st try was not clean because a portion of the code diff
made it into the pre-commit patch to add tests. This should
be the same end result without the muddied code diff.
Original commit message:
In cases with matching extends, this allows changing an 'add'
into an 'or' and narrowing the 'or' which then simplifies to
a constant.
In cases with opposite extends, we just convert to an 'or'
currently, but that could be reduced too.
