Nikita Popov 45226d04f0 [InstCombine] Reuse icmp of and/or folds for logical and/or ...

Similarly to a change recently done for fcmps, add a flag that
indicates whether the and/or is logical to foldAndOrOfICmps, and
reuse the function when folding logical and/or.

We were already calling some parts of it, but this gives us a
clearer indication of which parts may need poison-safe variants,
and would also allow to fold combinations of bitwise and logical
and/or.

This change should be close to NFC, because all folds this enables
were either already called previously, or can make use of implied
poison reasoning.
