Change subject: IMPALA-15312: Say when HBO changed a join's build side
......................................................................


Patch Set 2:

Fair point. I added this after HBO changed the build sides in a query while the 
operator counts stayed the same. But it only explains the local inversion 
decision; the input estimates can already include HBO effects from below. The 
wording is too broad, and I'm fine dropping the note if this is too specific 
for EXPLAIN.
